I would except front bumper,bonnet due to stone chips etc but i can't see any sence in having both quarters and doors done only thing that springs to mind is that it may have been keyed buy some jealous git what colour is it ? some colours are very hard to match .
It could be coincidence but both rear quarters and the knocking from the rear
Unless you can negotiate a big discount, I would be inclined to walk away.
It may sound odd, but personally I would always prefer to buy a car with paint damage - or even dents - over buying a car that had a full or partial respray.
If you buy a car still with its original paintwork, you know what the car looks like before any remedial work is done. With a resprayed car, it is impossible to assess the scale of the original damage, the scale of the repair, or the quality of the work. And you won't have a warranty for the repair, either.
I would suggest walking away from this car.
Thanks, folks. Decision made. NOT BUYING this one.
I forgot to mention that the seller was livid after the inspection when told about these issues. He admitted to the mechanic that the rear quarter had a dent when he bought it and had it fixed as who would buy a dented car. I suspect he bought a cosmetically abused car for dirt cheap at the auction and spent a grand or so getting it all nicely dressed up. After the inspection, he asked me to decide then and there else he wouldn't sell it to me even if I paid 100 grand later. I sought time until tomorrow and I now see he has raised the price on AutoTrader.
Definitely walking away with the following lessons:
1). If not a motorhead, buy a pre-purchase inspection when spending that kind of money
2). MB Approved Used CAN'T be blindly trusted --> to be honest, this disappointed me more than anything else as this was my safe Plan B
3). Ring up dealers, companies, garages that you see in any printed service history but not in DSB --> more often than not most of them will happily verify the service history (if they have a record of it) and, if produced with V5C, can also email the history to you
4). Always check with the amazing people on this forum
