Jerry DeJesus demonstrated exceptional professionalism
Jerry DeJesus demonstrated exceptional professionalism and expertise throughout our experience. It was truly a pleasure collaborating with him. He took the time to address all of our concerns as parents of a new driver and successfully guided us in finding a car that was not only equipped with numerous safety features but also remarkably affordable. We extend our heartfelt thanks to Jerry and highly recommend him to anyone in search of a vehicle.
One very awesome vehicle.

Just as promised. A great used car deal!
Saw vehicle on the internet on a Sunday. Called and AMY answered. Based on her accurate information she invited us to the lot the same day. We drove 2.5 hours and test drove the Honda CR-Z. AMY made sure all of our questions were answered. The car was an excellent deal for the price offered. The car did need brakes and a light. AMY made sure the repairs were done to perfection. She communicated via text over the next few days. Always answered instantly. The car was ready when they said it was. Everything completed as promised. Paperwork was painless. By Wednesday evening I was home with the car! AMY was a professional, the business did what they said. No Gimmicks, no false promises, no issues!
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Great overall experience
I purchased a 2009 Nissan Rogue on 10-11-12. It was an easy, actually fun experience. The sales man was not pushy, it was an easy process and everyone was very helpful. I love my new car. I would recomend carmax to anyone who wants a stress free car buying experience.
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Found the specific, rare car for which i was searching.
Found the specific, rare car for which i was searching. It was at Blasius pre owned. I had never heard of them so I took the trip from NY to see the car. The car was as advertised and I bought the car. 3 days later I went back and took delivery. Every part of the transaction was great. From the moment I walked in I was treated respectfully and everyone there is so pleasant. There were no games/nonsense just a straight, easy deal. No upsells, no hidden fees, it could not have gone smoother. I buy lots of cars and highly recommend Blasius. Special thanks to Adam Betancourt the salesman and Bobby Fernandez the GM for making this such a great experience.

Jerry is amazing!
Jerry is amazing! I really enjoyed finding my car online, and when I left a message about the one I was interested in, Jerry responded that same night. He even followed up with a text the next morning to let me know he’d check to make sure the car wasn’t already sold. Jerry—and everyone else at the dealership—treated us with genuine kindness and respect. I absolutely love my Rogue, and the color is beautiful! If you’re looking for a used car, I highly recommend coming here and asking for Jerry!

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

I bought a 2018 Nissan pro x a little over a year ago.
I bought a 2018 Nissan pro x a little over a year ago. I drove from ny to look at it it was clean except for front bumper was hit in corner and paint was scraped. They repaired the damage perfectly by the time I picked it up. I was impressed by their professionalism. The only thing that I thought was a little extravagant was the dealer fee. We negotiated a fair price and now it’s mine. I’ve had the vehicle for over a year and it is flawless. I felt I needed time to make a fair judgement of the vehicle before my review. I would not hesitate to buy another vehicle from thi dealership

A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.
