I called and talked with Steve.
I called and talked with Steve. Ten days later I went and checked out the car in question. It looks like I will be "pulling the trigger" and buy. He was extremely knowledgeable and kind. A true pleasure to deal with him. A "gentleman and a scholar"! I'll be back.
So far so good
The truck runs great. preformed exactly how I need it to. Has everything I wanted except wireless/Bluetooth an back up camera. But all that can be installed later.

Highly recommend, very reliable.
Highly recommend, very reliable. Bought my Nissan from them and the customer service is great
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.

Amazing Dealership
Kris and Joel in Blairstown have outstanding customer service and are AMAZING! We totaled a vehicle and within a couple of days they had us back on the road. They answered every question we had, treated us very fair, and continue to help us every way they can. I can go on and on about how happy we are with them and how smooth of a truck buying experience we had. If your looking to buy new or used i would choose this local small town dealer!

Pleased Customer
Mr. Sherrod has no idea how much I appreciated him working with me. I bought a really nice Jaguar from Platinum Collection about 6 years ago and I’m still receiving compliments on how nice my car looks and ride. I am still very pleased with my purchase.

Great dealer!
We already knew what car we wanted to see at the dealer when we went there. Austin was our salesman and found the car we wanted and let us take it for a good test drive. He sat down with us and went over what we thought about it and then started working on financing with us. Mike Phelps, the finance manager, then took over. He was great! He contacted some financiers and found the best rate for us. He did not pressure us to get anything we did not want to get. He got us a good payment. We would not hesitate to recommend this dealer, and we would also go back again.

My car developed a problem, (engine light stayed on) and
My car developed a problem, (engine light stayed on) and reduced engine power. The service department set a date and time to bring my car in and offered to provide a loaner car. I brought my car in on the scheduled date & time. The loaner car was washed, gassed up and ready for pick up. The repair was done in a few days; part of the repair cost was covered by warranty and my car runs great. The service department made this a painless process.

Out of state sales not a problem
I live in Ohio but was looking for a preowned 2020 Corolla Hybrid in the color I wanted. Ron S was my salesperson and was a pleasure to work with. He was very helpful, cordial and responded quickly to my questions. Andy in the finance department was also friendly, quick and efficient. They handled the paperwork so I could get the car titled and registered in Ohio. They also were very accommodating in arranging for delivery of the vehicle. I am happy to have a certified preowned Toyota. I would buy from this dealership again without hesitation.
