Bottom line is if they have what you need, it's well worth the imperfections. You have to know a few things going in:
(1) book an appointment or you'll probably wait a lot. It's very busy on the weekends.
(2) The in-house financing is above market rate (so refinance it after) and it won't be easy to bring your own financing with you. So either pay cash or suck it up and use theirs.
(3) It does take longer than you'd expect to make a purchase once you give the okay. Expect 2-4 hrs
(4) They do have a short warranty, but forget that. You really need to thoroughly vet the car before you buy. Bring someone who knows cars if you don't. Approach it like a cash purchase from a private seller and take as much time as you need to determine it's mechanically sound. They won't pressure/rush you, and that's very good. If something isn't right about the car (things missing/not working), don't buy it. Assume it comes as is and they'll not fix it after the sale. Remember if there's a manufacturers warranty still running you can get the dealer to fix something that's broken if it's covered. But you're probably better off waiting for a different and better car.
(5) Do your homework. If you have questions about what features the car has, look them up by VIN before you go. There should be nothing they can tell you about the car you're looking at that you shouldn't already know.
