Speaking of Off Lease Only...
I live in central Florida and purchased my 2015 GSW S TDI/dsg from Off Lease Only in Miami last Dec. My GSW had a clean vehicle history with 40k on it and I paid 12,999. I had been searching daily for a blue one and bought it the very 1st day it was in inventory. Since they hadn't uploaded any photos yet, they did text me a few while we were en-route.
It replaced a 2009 Mazda 6 with a manual and that was the 1st car we purchased at Off Lease Only in West Palm Beach in Nov of 2012. I sold the Mazda privately on my own. The GSW is the 13th purchase from them between family and friends.
As for the dealer experience, there is no haggling on the price, they give trade-in values below rough KBB book value (I highly recommend finding another way to sell your trade - we have had good luck selling ours ourselves) but my girlfriend has traded there twice. The finance/business office is where they really grab you by the short and curlies and I refinanced mine at my credit union before the 1st payment was due. Which I had planned to do ahead of time because they "don't accept outside financing."
Of the 13 vehicles that friends and family have bought from them, I have been present and sat through the entire purchase process for 11 of them.
A friend did purchase an extended warranty from them on her 2012 Escape Limited, and would later find that (like nearly every other extended warranty - I tried to tell her) it's almost worthless. My mother bought their GAP coverage on her 2014 Jetta, and has since complained that she couldn't refinance hers without coming up with about $2,000 (roughly the amount of the GAP insurance.) Naturally, I don't recommend either.
I do recommend Off Lease Only because it's difficult to beat them on price, they offer full vehicle histories right from the the website and they usually have a large selection. But I always recommend looking over the car very well because vehicle histories are commonly incorrect, along with a thorough test drive as the cars all come from auction. Many cars are in above average condition, but I have seen several I was afraid to test drive. (This is the same for all dealers)
Off Lease Only is almost always crowded and CrAzY busy, so have a meal before you go. I'm not thrilled with their finance office, but it's not any worse than any other dealer and we've been satisfied with most of our transactions. Once you have selected your new vehicle, count on waiting an hour or two (or longer) to get into the tiny little office and you WILL be in there for 30-60 mins. We have bought cars from them in Palm Beach (4), Orlando (6) and most recently Miami (3). They also have a location in Ft Lauderdale and another planned for Tampa and we are about 2 hours from all of them.
One of the best things about them, is that you can cross-shop every car on your list all in the same place. I'm also addicted to their website. But be prepared, it's not like a normal dealer.
With buying any used car... Caveat Emptor.
