Disapointing selling experience!

I recently wanted to sell my car, 2013 BMW 328i GT to Weelee. I was informed by the buyer that Weelee does not buy cars that had been painted on more than two panels, even though on their advertising they claim that they buy ANY vehicle. My vehicle was repaired to top standard by a BMW approved repair shop and is no doubt in immaculate condition with a full service history. Sad to say my experience was disappointing. Surely if you claim that you buy any car this is what you should do. I viewed many vehicles on their floor with less than desirable (dents and scratched) but that is fine. Don't sell a car to them if you look after your car it seems. Surely they should ammend their advertising and warn potential cusomers to stay away if their vehilces had been repaired.
