I had the same experience in the past with another Tiguan I was given as a like for like, except this one was dirty inside and out and covered in marks and bits of trim loose, lots of small car park dents and I was told sign here there’s no damage on the car?
when I asked what about all the obvious ones even I could see on such a dirty car? he said it’s fine sir it’s all wear and tear.
I only had the car two days and they collected it, the guy said all ok sir, i had a dig at him joking where do I send the dry cleaning bill to as it was delivered with the interior so dirty.
He said nothing took the car and that was that, if I was paying for it I would have refused it, but I thought great I can get rid of all the things I wanted to take to the dump with no worries, so apart from dog walking duties and going to the tip 3 times that’s the only miles I put on it.
