I bought a GT Premium/California Special and love it. It has more bells and whistles than any Mustang I have ever owned. The Mustang is well insulated and is a solid vehicle.

Living Large
After a negligent driver rear-ended my other car, I bought a 2022 Mustang GT Premium with the insurance money. I had a 1979 Mustang Cobra years ago and loved it. This is a great car, too. Fast, comfortable and beautiful. I haven't driven it in snow yet and have some trepidation about that but otherwise I'm glad I bought it. There are only three things I don't like: the car payment (who does?), the gas mileage, although I can get 30 mpg if I drive 58 mph, and there seems to be some high school kid at every stoplight who wants to race. This is definitely a car worth buying if you're an empty-nester, going through your mid-life crisis or single and don't have to haul much in your trunk.

Easiest buying ever
The easiest most, efficient car buying experience we have ever had! Jeremy Guijosa was communicative and professional. Shopping here was worth the three hour drive
Great addition
I bought this car as the baseis of a new hobby build. It had the performance options I wanted and was an automatic. Two items the dealer failed to disclose were worn tires and two curb checked wheels.

Everyone has been very conscientious and courteous
Everyone has been very conscientious and courteous checking back with me to determine what I want and if I was aware of the age of the vehicle. They also informed me that their service department wanted to work on some issues with the car and that they would let me know what they did and what work they believe still needs to be completed.
I have a premium Yellow 2015 GT convertible.
I have a premium Yellow 2015 GT convertible. Black interior (not charcoal gray) with a Black top. This car has the 6-speed automatic and therefore, it does not constantly shift up/down like the newer (lousy) 9-10 speeds. Mine includes the Ford Performance PowerPac 2 with RTR axle backs. With only 19,000 actual miles, this car looks, sounds and performs excellent. Would not sell it for any Corvette (have had 3 of them) nor any other Convertible with a 9-10 speed auto. Nope - This car is too nice to part with…

Have purchased a lot of different cars at different
Have purchased a lot of different cars at different dealers and the three I delt with there were great. Best experence ever. Derek , Adam, and Grant treated us like royalty. Purchased a 2025 Teguan for my grand daughter 11/14/25 and went back 11/15/25 and bought one for my wife. No presure sales and two the point , no haggle sales. I have probably purchased over 50 vehicles in my 78 year history and this is like sales should be. First time volkwagen purchases.
Best car I have ever owned
I bought my E320 Wagon new in 1994. Currently, I have 248,000 miles logged. She burns NO oil and runs like new. Replacement parts? Thermostats, exhaust muffler, battery, shock absorbers, fan belt, transmission case gasket .... that's all. Since new I have spent less than $4000 on repairs .. but I did repaint for $5000. She's beautiful, comfortable and envied by all who sees her. In the past 27 years I have betrayed her twice by 1) buying a new 2012 Audi 6 Quattro, which I sold after one year and went back to my garaged e320 wagon and 2) was seduced by a sleek and fast 2004 BMW 540 wagon. After less than a year I sold the BMW and went back to the E320. I'm looking forward to the next 27 years and 500,000 miles with my E320 wagon. The best feature of my wagon is visibility. In the 80's and 90's good cars were built so you could see out of them. Today's new cars are built to hide the passengers from the outside world. And you cannot see out of the either.

Great service
2014 Outback manual transmission and rear differential oil change was performed. It was done quickly.
I was initially looking for a used Golf, but the more I
I was initially looking for a used Golf, but the more I looked at the Beetle the more I liked it. When I found the one I ended up buying, it was love at first drive. This little car packs a punch with the 2.0T, and will throw you back in your seat. It’s an absolute blast to drive. Handles well around town and on the interstate, where it could easily get one in trouble since it wants to GO. The same engine as is found in the GTI, so this should be unsurprising. Easily gets 30+mpg on the highway when cruising along, typically around 20-25 city. These cars handle city driving just fine, but they are meant for the freeway in my opinion. I find the interior to be quite luxurious. Heated leather seats (not available in the Golf) with plenty of storage compartments. Not many frills, just a sleek and mostly practical dash. The trunk is big enough for grocery runs, and the rear seats fold forward for larger loads. It’s not going to haul large appliances or furniture, although it could possibly carry some bigger stuff on a roof rack. The Fender audio system is impressive, wouldn’t change a thing about it except it could benefit from an updated head unit with CarPlay. This hasn’t been an issue for me. I think the car is a real looker, it turns heads and has drawn the occasional compliment. My used model had some imperfections, but it’s still a great looking car that I want to look after and keep for as long as I can. It feels well built, the doors close with the satisfying weighty thud of a premium vehicle. Overall, I am very happy with my 2013 beetle. It’s not only fun, but it seems to be reliable with a couple caveats that some owners might not be aware of. The 2.0T engine is designed for premium fuel, using regular will eventually damage it. The 2.5 can run regular, but I believe the 1.8T will also want premium. The reason for this is lower octane fuel will cause detonation in these high compression engines. If you don’t know what detonation is, just know it’s bad. The oil needs changed more regularly than the manufacturer recommended 10k miles. 5k to be safe, 7k at a stretch. This is especially true for higher mileage vehicles. Speaking of stretch, there is a known issue with some 2.0T engines where the timing chain stretches over time and many miles, so if buying used that’s something I’d have a mechanic check out. This is an expensive maintenance item, but IF it’s needed, getting it done along with the tensioner and a new water pump for good measure will ensure that the new to you Beetle is reliable for many years and miles to come. The other issue is carbon build up. Getting it cleaned out is not as spendy as the timing chain but it’s also not a cheap fix. I believe this can largely be avoided by using top tier fuel (it contains detergents that help with this) as well as regular oil changes and some regular spirited driving. Would not recommend this car to someone who mainly does town or city driving, the 2.5 engine might be better suited for that. According to my research, the 2.5 is quite bulletproof BUT it’s not good for any engine to be driven at low RPM all the time.

Lots of fun, especially with the top down
Great 2-seater, lots of fun with the top down. Surprisingly, has ample storage. Great looking car IMHO. The retractible top is a plus, much better than a canvas top.

Went to look at a Rav 4. IT greeted me and asked what options were important to me. He answered my questions and explained everything to me. The financing part was painless. IT set up my phone for me and explained all the features of the car and showed me how they work. I did not feel pressure and the entire experience only took about 2 1/2 hours. I hope that my service experience goes as well.

Happy is Her Name!
We bought a used 2020 Cooper S convertible in December 2022 with only 6,000 mile on the odometer. It is a blast to drive! Don't plan on taking passengers unless they are very small children or pets. Looking forward to warmer weather and many cruises although we did put the top down and took a spin in it on Christmas day.
