I came across Jim's dealership while seaching the internet for a used SUV. I purchased a 2002 Chevy Blazer from him that was exactly described on his site. The truck was very clean and in excellent operating condition. It is still my daily driver a year later with zero issues. Jim made the buying process easy including tags and regstration. He is honest and upfront and a great guy to deal with. I would recommend him to anyone searching for a great used vehicle at a fair price.

My husband and I were searching long and hard for a truck. We live over an hour away, and drove out to Williamson Auto sales, on the good word of Jim. I must say, what a truly amazing experience. Jim is truly a one of a kind individual. He's down to earth, honest and has plenty of knowledge. Thank you Jim, we will be passing along your name! Thank you! If I could give 30 stars, it would start here!

My wife and I purchased a 2002 GMC Yukon from Jim. We were treated very very good. There was a problem with the rear end on the vehicle Jim took care of it immediately. Jim always responded when I called and followed through. I would definitely purchase another vehicle from him again. He definitely cares that you are happy and satisfied.we love our yukon it was an extremely good shape for the year.

Just purchased the most awesome GMC Yukon from Jim. Couldn't have met a nicer guy to purchase my new vehicle from. Everything he said on the phone about the vehicle was exactly what it was when I saw it. Couldn't be happier. I highly recommend Jim and Williamson Auto Sales to anybody needing a GREAT used car or truck. Need a car or truck look no further than 52 Donovan Street... call Jim, you won't be disappointed!

The owner, Jim, was such a nice guy, a decent, honest, regular guy. Easy to comunicate with, he was clear and forthright. Such a breath of fresh air! The car we bought is in excellent shape with low miles. It is10 years old though so we noticed 2 minor problems after we got the car home (burnt out bulb and a tiny star on the windshield), Jim unhesitently took care of both with no trickery and a pleasant attitude. I will have no trouble recomending him and I will be back when i need another great car! Thank you Jim!

Great experience! I bought my Ford Escape through Jim a few weeks ago and after months of searching for a car I was so pleased to have such a smooth and pleasant buying experience! I love my car and Jim was very upfront and honest as well as easy to get ahold of. My car was SUPER clean and looked like new when I bought it. I would definitely recommend purchasing a vehicle through Jim. Kristen D. Canandaigua NY

Recently bought a 2004 Impala for our daughter. We had been looking for a month or so and came across this online at Williamson Auto Sales. Watched it for a few days and then called on the car and set up an appointment. The car was ready to go when I arrived and I had a good test drive. Not one of those up the street and back. Jim was easy to talk with and I did not feel rushed or pressured at all. Sent a pic to my wife and daughter, both liked the car so we made the deal. Picked it up a few days later and it was plated and all the paperwork ready to go. Took about ten minutes and no trip to the DMV! Easy transaction and great customer service. We will definitely check out Jim's inventory next time we need a vehicle. Thanks Jim!

I am very happy with my purchase! I recently got into an accident and needed to find a decent, well maintained vehicle. I was able to find my new car through Williamson auto sales. My car had one owner with very low miles and very clean for its year. He finds great cars and is able to give great deals for what he finds. I could not have been any happier with our experience at Williamson Auto Sales. He is very personable and trustworthy, and I would definitely recommend this small car dealership to anyone. I bought my car from Williamson Auto Sales and felt very comfortable with my decision as I knew that the car was well maintained and freshened up and inspected before being ready to sell. My experience was very positive, and I thank Williamson auto sales for being extremely fair and going beyond my expectations. Thank you Jim for your service and for your warrenty! Jim is a pleasure to work with and he fulfills all promises he makes. This is the best price you can get for a dealership!

Wife's Subaru blew the motor...needed to find a car to drive until I could afford to repair it. Nothing local worth while...eventually found Jim after searching 3 hours away from home with google. I messaged him through his website and he responded immediately (refreshing)! Made an agreement over the phone. Helpful, accommodating, and honest. He made promises to my wife and I before we made the 3 hour drive...he kept every one. Communication was great. Test drive and paperwork was fast and pressure free. I felt like all he cared about was making sure we were satisfied before we left. I actually drove the car home and couldn't be happier! As I'm always a little skeptical when buying an older used car, I took it to my mechanics (national chain repair shop) to have it looked over for any issues. Their response "...you got a deal, required stuff was addressed, there, car is in great shape and clean." Simply put, they could find nothing wrong that hadn't already been taken care of before he put it up for sale. When one very minor warranty issue did arise, he dealt with it immediately and to my satisfaction. Wish he would relocate to St. Lawrence County...we could use a dealer like him up here!
