First car buying experience and it wasn't too bad ...

First car buying experience and it wasn't too bad at the time. Price negotiation took very long (at least they have coffee?) and then seemed rushed/impossible to do better. Selling the car now and realizing we super duper got ripped off. It seems true that car sales is a cruel business and the 'nice' salesmen don't really care and will take advantage. Thanks I guess for teaching me a lesson.
