I picked mine up from Jcb gillingham on a dull day and it all looked fine, next day when the sun was shining it looked dreadful, whole car was covered in fine scratches, especially bad where they had taken foam pads off the doors and rubbed off whatever sticky marks where left.
I contacted my salesman but he wasn't really interested, that's one of the down sides with living 300 miles from your dealer
My advise would be to do the prep yourself, every time I look at my new 25k car on a sunny day it really pisses me off. :cry
