Willis @ AC Motors
Great services and easy buying process!! This is my second car in three years from him. Can’t wait to purchase another vehicle from him!! Cheers
Good truck if you do the right things
The best thing about this truck is the fuel economy. Bought brand new in 2012 and when the truck hit 35000KM the fuel economy improved. I had heard about that before but didn't believe it. Beware, these trucks are known for transmission shutter and shifting problems like every GM product ever. Do not flush the transmission ever. Pull the pan and replace the oil three times every 40 of 50 KM. It costs a bit but the tranny will shift much better and last. The door handles are garbage. They cost 25 bucks on Amazon. Changed two now. Changed washer fluid sensor. Front breaks and rotors are cheap. Replace with high end aftermarket when they go...and they will. Over 200 Km on this vehicle now. Motor is strong and the truck is still holding up well. I would give it a 5 if GM would get their transmission issues fixed one day. A little higher quality front end parts would put them over the top. Good ride, roomy and comfortable.

My experience at Cars R Us was good.
My experience at Cars R Us was good. Marquez helped me out and he was cool to work with. Purchasing the truck went smoothly and negotiation went better than I thought it could. I wish I would have taken a longer test drive, as I found a few things about the truck after purchasing. But the men and woman at Cars R Us seemed like great people. Id recommended checking them out if you’re on the market for a nice used vehicle.

Everyone at Shifferly Automotive was incredibly friendly.
Everyone at Shifferly Automotive was incredibly friendly. I was greeted immediately when I walked in the door. I told them I saw their Subaru Crosstrek on cars.com. He offered me a test drive, and handed me the keys. The car was in awesome shape, and the price was right in my budget. I think I met the whole Shifferly family while I was there. They made it such a pleasant experience.

Honest Service
I have had a problem with my car for quite some time. I was told I needed a power steering pump. I called for estimates. I went with Mike at Tradition Auto. He called and told me I did not need a power steering pump but it was something totally different. Guess what my car is finally fixed. I will not go anywhere else now. I highly recommend Mike at Tradition Auto. Ladies you can trust this shop.

Looked all over the country and ended up here.
If you know what you want,and have the means this is the place. The Ken and Brian combo is the Best. If you want to haggle about price this is not the place. Prices are set to go against Nationwide market. If you do your research and they have the Vehicle, you're looking for this is the place. In my humble opinion.
