I walked in and was treated by Alex Duarte. He was amazing and very personal. Allowing me to share what me needs and wants were along with understanding my situation. He took the time to listen and go above and beyond to make it all work!

I only write reviews for truly exceptional businesses.
I only write reviews for truly exceptional businesses. Truly great buying and post-purchase experience. My wife fell in love with this Jeep, and Dan let us take it for a test drive “as long as you want”. We didn’t abuse the offer, but went for a healthy drive. Loved the manual, but you always have to wonder if the prior owner wore out the clutch, but no problem as Dan had already installed a new clutch as well as a couple new tires and a couple other things. We returned it and said we wanted to sleep on it. There was no hard sell at all. I called the next day to see if I could bring it to my regular mechanic. “No problem”, said Dan. I took it to my regular guy half expecting to get a report back about a half dozen things that were either worn out, broken, or just missing. As it turned out, my mechanic came back saying, “we couldn’t find a single thing wrong!” He seemed disappointed, so I know he tried to find anything. Even with that, I was a little nervous about the purchase - you know what I’m talking about, that “Am I just buying someone else’s problem?” feeling. We needed a car, my wife loved the car, it came back with a clean inspection, and the price was very reasonable compared to other options I reviewed online. So we went for it. Dan made sure the car was detailed and handled all the registry stuff. Not two days after we got delivery, the engine light comes on. I’m thinking, “Here we go….this is going to cost me”:( We called, and Dan was genuinely horrified, “Bring it in, I’ll take care of it.” Full stop right there. Awesome! We had already paid for the car, and I was not expecting that response. Dan provided a loaner and took what I would call exceptional care of the car not only fixing the what-ended-up-being-a-minor-issue, but also doing a full check, again, post-purchase, just to make sure it was perfect. I waited a month to write this review just to make sure nothing else happened, and it hasn’t. The car is great; my wife is happy. As I reflect back on the whole buying and post-purchase experience, I am in awe. How many companies these days not only ‘do what they say they will do’ but also add in a few ‘surprises and delights’? If you are a serious buyer, go here and buy from DRIVE and sleep well at night based on your good decision made.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.
