I was going to drive 2.5 hours one way to look at a Benz we were interested in purchasing and while there get our Mercedes fully detailed . I requested a loaner as I wanted to make the most of my time in town while ours was being worked on. I could have returned the car as soon as ours was finished. I was told no, it was not possible and I would need to wait up to 3 hours at the dealership while mine was being detailed. I was also told it would take 3 hrs to do the pw if we decided to purchase the car and we could drive it. Guess, what not coming.
