2019 GMC Sierra 3500 review
Lane Departure saved me on a few long trips. Seats are extremely comfortable. Fifth Wheel Prep made it extremely easy for my hitch installation. Amazing Sound System

Kearns Motor Car Co. review
This dealership has an impressive slate of exotic cars, I was just looking for a lesser jag. They treated me very well not pushy and very helpful. There were no hassles in getting to test drive the car I was looking at. When I decided to walk away there was no pushback or pressure to “ run the numbers”. Both the sales person and the manager communicate with me to ensure my experience was a positive one.

FRIENDLY COURTEOUS EXTREMELY HELPFUL HE ARRANGED FINANCING FOR ME HE ARRANGED DELIVERY TO ME I'M VERY HAPPY WITH HOW SMOOTH IT ALL WENT
2024 GMC Sierra 3500 review
This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued for 2024) and the only way to change it was to cancel and start over.....so black it is!! The truck is gorgeous and much larger than I thought! I am pleased with both exterior styling and the 2024 interior refesh. My only complaint is the seats, they are a bit firm.....still comfy....but firm. The GM sunroof is small, so small I passed on the option. Mechanically this truck is a pretty sound design. Another 50hp for the 6.6L gas engine would be nice, but 401hp is pretty decent. A PTO offering in the up level trims would be nice, as would a larger/dual fuel tank option is needed (GM is the only one that doesn't offer one), and a factory level in the front, and while I am dreaming a front locking differential. GM could up thier paint game, when approaching 90k I expect better paint. Value wise it is as good if not better than the rest of the over priced trucks on the market. Rumor is 20K per unit on average goes to the UAW pension, that's why your 50k truck costs 70k. In closing I have zero regrets other than the color, but I needed it immediately so here I am.

Ourisman Honda of Frederick review
I've had two excellent experiences with Shockley Honda when buying a car from them. The first was a little over a year ago and the second experience was last week. I found an excellent 2018 CR-V at a very reasonable price, but had a disabled trade-in over 65 miles away. Shockley not only gave me a fair amount for the trade-in, but also arranged to both deliver my "new" vehicle and pick up the "old" vehicle, saving me quite the effort to arrange things otherwise. My sales guy was Chris Collinson and handled everything from start to finish. There was no high-pressure sales or hidden add-ons. There was no pressure to use their financing when I told them I had my own. I appreciate the respectful way I was treated. It really seemed like I was his only customer that day when I knew I wasn't. Plus, it didn't stop there! Chris made the delivery from Frederick to Parkville himself and has followed up with me to make sure all is well and that I am happy with the car and his service. I highly recommend Shockley to anyone in the car market. You won't be disappointed! Be sure to ask for Chris!

Cody was AMAZING!!! It’s rare in this industry to find people who are Genuine and Honest. That is exactly who Cody is, he worked hard to get me in the car for me! He communicated responsively and had a finance team that complimented him. His service is high end, personal and made me feel like the most important person. Outstanding job Cody, your a friend for life.. I will be telling everyone to go see Cody! He goes above and beyond..you won’t be disappointed 😀🥳🎉

Lime Ridge Auto Sales review
Great guys to work with from first contact to picking up our truck. Friendly and low pressure atmosphere. Would recommend to anyone looking for a good used truck!
2018 GMC Sierra 3500 review
An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

Auto Connection of Lancaster review
I was looking for a slightly used Jeep Wrangler. I've seen Auto Connection and the sweet vehicles they had. Through an acquaintance, I was hooked up with Jeremy Horst who helped me trick out my new Jeep. I started with a base model 2018 Wrangler Unlimited Sahara JL—I was able to pick out my wheels and then Jeremy guided me with what lift and tires I should add. The entire process was seamless and was actually fun and exciting! Jeremy delivered on his word—a gorgeous Jeep! Thank you Jeremy for all your help and guidance. I would recommend Jeremy and Auto Connection if you are looking for a sweet ride!

Great place to buy a quality used truck. Fair and honest sales staff and I would not hesitate to recommend lime ridge auto to anyone. Loving my 2006 ram 2500 with the 5.9 and six speed manual. It took me a while to nail down one of these trucks and I could not be happier. Was definitely worth the drive from vermont

Lime Ridge Auto Sales review
It's been 2 mos since buying my '11 GMC DENALI dually from Lime Ridge. I live nearby and am always impressed with their inventory, so after deciding to upgrade my ride, I reached out via their website and Jamien called. This was my 1st diesel purchase, so I had many questions for him. Afterwards my wife and I decided to visit the dealership, where we test-drove 5 different trucks. It turned out to a very busy day for the dealership, but Jamien was patient and gave us the time and space we needed to make our decision. He also hooked me up with some performance mods as part of the deal, gave me a fair price on my trade, and has even taken care of some issues I discovered after the fact...at zero cost! Jamien has been great to work with before, during, and after the purchase. I have been 100% pleased with this place and highly recommend them. In a world full of used auto dealers, these guys stand out above the crowd!

Lime Ridge Auto Sales review
Great experience! Fantastic dealership with a museum like feel. They took care of one minor problem I had with moisture in a headlight by replacing the headlight while I waited. Absolutely fantastic people, great service, quick paperwork turnaround.
2020 GMC Sierra 3500 review
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.
