Tim, George, Joe and Frankie were amazing. Answered all of my questions and helped me through the process with poise and reassured me along the way. Will definitely be shopping for my cars through them from now on!

I keep seeing this car show up I wish it would update right away that
the car was not available! People who I have dealt with there are
very friendly/knowledgable.

Called before I went and was told the cart was still available. When I got there it was no longer there because it had been sold.

Though I have not yet purchased a car, Diamond Auto Cars was one of the few online dealers
who followed up with me. Sarah checked to see how close I was to buying something. Diamond
Cars and their '98 Corvette are still in the running! Many others don't bother to even acknowledge
my inquiries.
watched it for a week or two - contacted the dealership, set up a test drive. They repaired the
minor things I wanted, were flexible on price and had it ready when they said. Would recommend
and use again.
