I had always paid cash for pretty much everything. A car lot had a truck I liked and Credit Acceptance was their lender. Down payment wasn't bad, payments weren't bad and a year later my credit was almost non-existent to 740. Their customer service was always friendly and helpful. I can't say how they react to late payments as I had mine taken directly out of my bank account. I found something I liked better and traded in my truck and tacked the negative equity onto the new car (almost a wash as I got the car for the right price so I didn't break it off in myself). They are a good jump-off point if you need something to drive and want to establish credit. Can't say a bad thing about them.
