Used cars for sale by owner in Boulder, CO

Great looking, fun to drive 4x4, super reliable, leather interior but strong enough for 2 dogs and 2 kids. Goes anywhere. Roof rack easy to use. HAs all the electronic helper (BSM, cross traffic alert, lane keeping, adaptive cruise). The downside is the gas milage. 16.5 to 18 mpg depending on time of year & type of gas (summer vs winter gas). No service issues in 45,000 miles but they did some fuel pump recall when I was in for an oil change

I was searching for a specific vehicle and I found a few on cars.com. 2020 F-150 Super Cab 2.7L Ecoboost, 10 speed transmission. At first I was concerned since I've never had a truck with a small V6. I was looking for good HP and good MPG. I liked the sporty trim STX look. Great acceleration and great MPG. Much better than my previous 2006 F-150 5.4L, which was a great truck, but it was time for a change. I do recommend this vehicle if you want MPG, power, and great towing capacity.

My 2010 had 317,000 miles when I bought my 2021. I absolutely love the changes that toyota has made. My 2021 is a perfect truck for comfort and reliability.

I bought this truck used from Long-Lewis in Hoover, Alabama, in July 2025. I like the performance, gas mileage, and drive modes of the 3.5 Liter Twin Turbo with 10 Speed transmission. Lots of interior space, lots of interior and exterior lighting in the right places.

The car was a buy base off of needing a car. I like this car and so far meets all my expectations. Tesr drove the car . Rides nice.

Great awesome cars in every aspect, comfort, performance, handling, smoothness, features, reliability (not in some models though) and especially safety. You get the best bang for your buck in Volvos. Only thing I would say is to stay away from the XC90 T6 (petrol engines) from 2015 - 2016. (Not sure if 2017 has these problems, as I havnt experienced anything from the 2017 models) I sell many of these Volvos But the petrol XC90s T6 from 2015 - 2016 are very unreliable because of being the first year of these models when they first came out. Had many experiences with failing superchargers ($4k to fix ) evaporator failing ($5k to fix) and also these engines have a known fault that the pistons don’t inbed in properly in some of the engines and it burns massive amount of oil. (Did a test in a customers car, was burning about 2L of oil every 1000km) Also comes with a few hiccups here and there with coolant leaks, and oil leaks etc. I’ve never had a problem with the XC90 D5 (diesel engines) as they seems much better because they don’t have the engines failing or a supercharger in these models. This have the failing evaporator but this item was the least part failing out of everything I mentioned. I hope this information has helped out some people who are deciding to purchase a Volvo 😊

I’ve had my M3P for 5 days and I freaking love it! Controls take some time to get used to where everything is. I’ve had maybe 30 cars and this is my favorite by far. I highly recommend if you’re in the fence, just buy one. You only live once!

I've own a 2024 Kia Sorento SX Prestige for two months and have been completely satisfied with it. It has more then enough power. For those who have an issue with the dual clutch transmission, should understand that it is a computer controlled manual transmission. It will respond a bit differently then a conventional torque converter type. Some have said it doesn't shift smoothly at lower speeds but I personally have had no issues. I live in Pittsburgh Pa, which has a hilly terrain and bad roads and no problems so far. Stop and go traffic has been a none issue. Very smooth shifting transmission! The ride quality is very good. A little on the firmer side, but it takes large bumps well. Seats are comfortable and the interior has a premium feel. I've own a 2019 Honda Pilot Touring and in my opinion, the Sorento is better in every way except for the room in the rear. And where it excels is in the features it offers! It's much better equipped than Pilot at a less expensive price. It has so far been the best car I've own in my fifty years of buying cars! Everything works! Sorento has been one of Kia's more reliable vehicles. I highly highly recommend!

Great until the extended warranty ran out And 2023. Cost of replacing a valve and associated work was $5000. Shakes if rear windows open from wind. Aerodynamic so so.

I've owned this car for almost 5 years, bought it with 104k. Now it has 230k and still running good. Never owned a car with these many miles on it. All I've done is regular maintenance and 1 oxygen sensor.(Make sure you don't buy aftermarket, won't work well) Love my car, still holding up very well and I believe I could easily get 300k or more. Was planning on selling it but I might as well keep it until it dies.

This car has blown me away. It has all the bells and whistles I wanted and drive like butter! The color is perfect and the rims are bomb! The interior is clean, and very well taken care of.

I bought my 2017 in spring of 2020 with 27k miles for $27k. I was specifically looking for a TRD Sport, manual trans. The Tacoma is the only manual trans truck produced anymore. I currently have 80k miles on it now and the blue book still shows it at $23k-$24k. I have not had any issues with it. I have done my own maintenance (oil changes and just recently front brake pads). The 2017 was the last year before they added all the safety stuff with the cruise controls. I'm glad I don't have that stuff. I also have the map system in my factory head unit and don't have to rely on the Apple carplay or Android auto apps. There was some discomfort in the seat. It was easily resolved with items that can be purchased to adjust the seat to your liking. There are a lot of complaints on the power and fuel mileage. Really?? Its a truck. Its not a sports car or compact sedan. Its not going to get the greatest mileage or set land speed records. If you want something that always starts, never leaves you stranded, and you can count on everyday, this is the one. If you want something that you want to spend a bunch of money repairing, you may want to look elsewhere.

The perfect car for our needs: a small SUV with relatively high (4400 lbs) towing capacity. Only the BMW X3 has the same combination. The Q5 is well appointed with high quality materials. It feels very solid on the road, with adjustable driving modes (dynamic, comfort, etc.). It has surprising power for a 4-cylinder engine and surprisingly good fuel economy. We purchased this vehicle used with some remaining factory warranty, which we haven't yet needed--all systems are working perfectly.

Design beautifully, very reliable 3.0 L diesel engine it has a lot of torque, I’m in love with it, I will definitely buy another one

The sound system is amazing. I upgraded my old Mazda 3, 2015 to a 2023. The inside is much quieter. I love my heated seats. We've owned many Mazdas and have loved them all. The reliable little cars with great gas mileage.

We purchased this 2013 Honda Civic new , it now has roughly 135,000 miles now in January 2025 and has only received regular service maintenance. It has not needed any repairs , with the exception of tires, two battery replacements , and proactively replaced brake pads and rotors.

I purchased this 4Runner new, have only driven it moderatelybut far back into rarely ever traveled areas — definitelyfar away from any crowds. I do all maintenance myself, and there is extremely little of that. I have only replaced the original battery once. It handles very well in all situations. I did and strongly do recommend getting the factory high quality stabilizer system. Mine is a 4x4 Trail Edition and I ever so greatful for that. That provides truly complete 4 wheel drive but only when needed. Being a car mechanic when young, a Marine Colonel and a retired Professor of Plasma physics and Quantum Electrodynamics, I carefully studied all vehicles and options far in advance. The Toyota V-6 engine is famous for its extreme durability as is every part of the vehicle. I did, as a possibly excessive caution, replaced the perfectly good radiator with a larger, no–plastic radiator possessing far better transmission cooler. Also being a private airplane pilot for over 65 years, I have long ago learned to be pro-active rather than reactive. Silicone hoses and best quality German full synthetic oil in engine, transmission and both differentials. The European oil standards are far beyond American and aggressive testing has proven that beyond any doubt. I have also replaced the cheapy passenger car tires and wheels with full beadlock, wider, negative offset wheels (all 5) with Toyo 8-ply rated 275/75–17" tires (34"), improved the factory shocks with King 2-¾" shocks & springs, et al. Yes, I also designed & built high quality fore & aft stainless steel bumpers to carry an 10mt hydraulic winch and double swing out locking rear bumper to carry 3 20 liter NATO gas cans, high lift jack, 4 traction panels and the oversized spare tire. The driving and riding quality is genuinely wonderful. This vehicle will out live both my equally fantastic wife and myself, as well as the next series of owners. Just nothing ever goes wrong with it (full skid plates help). To date, I have never known of a more practical, pleasant, reliable vehicle, and we have gone to some very 'dicey' places without any fear of getting stuck or damaged. I honestly have never even heard of any vehicle remotely as reliable and comfortable even for long trips as the 4Runner. I had a 1987 4Runner but the 4 cylinder engine, while excellent, was just not powerful enough, although I did much prefer the standard 5 speed manual transmission over the current automatic transmission. In approximately 400,000 miles over 27 years, I only replaced the battery twice.

Just bought this truck with 42000 miles hopefully it treats me good 12/16/2023 looking for a warranty company that Ford honors that’s not too expensive, bumper-to-bumper

I bought my 2017 Ecodiesel in April of 2018 at a significant discount from MSRP due to "Dieselgate" with VW and then modified software on these. They were held up for months so that the software could be corrected, so by the time they were available for purchase there was a massive overstock on them. With the complete re-design for the 2019 models, dealers were looking to get these moved out and offered big incentives to do so (up to $20,000 off). There have also been some recalls for a few things, but nothing that has seemed to go wrong on my vehicle, but I took it in to get everything addressed for the recalls. That being said, I haven't had any issues with the truck not working at any time and it is one of the most comfortable riding vehicles I've owned, especially on longer trips. The little diesel engine gets excellent milage on the freeway (about 28 mpg) and about 20 around town. Seats have coolers and heaters, the steering wheel also has a heater, auto start, good lumbar support, a nice sound system, "Millenium Falcon" style ice boxes under the rear passenger floor spots, and a lot of other features that even new trucks don't have. Plus I am not having to "rent" services that came in my truck like a lot of new vehicles force people into. It hauls what I need it to haul, tows what I need it to tow, and drives where I need it to go. Does what a truck should and with comfort to boot.

I bought this truck with 100000 miles already. Beautiful truck! I only have a couple of complaints. The ride, one can feel every pebble in the road! Shocks and better tires may help. 2x4. Need to add more things like memory seats and adjustable pedals, to the Lonestar truck and it would be perfect.
