Long story short, I had some fender damage after getting bumped while parked. Its been repaired but I see some cracks forming in the paint and at this point rather than go for a re-spray would just find a scrapped drivers side fender somewhere and swap it out.

Just need to confirm if I can shop around for all w211 fenders? only e55 and e63?

My car is a 2008 e63.

Yes. They are all aluminium

Ok great, so an 08 e320 front fender is the same as an 08 e63?

Any 03 to 08 w211 fender will fit.

No. AMG cars use different fenders than normal Mercedes.

Strange, everywhere I’ve been looking the model breakdowns for the fenders have included all models within the w211 family as LS mentioned earlier.

I can't confirm, but I think that all the fenders are the same for every W211 model. Rationale, why make several different fenders for every model, that just doesn't make any sense.

I can confirm that the w211 fenders are in fact the same. No difference between the e320, e350, e500, e55, e63.

in case anyone searches this one day or just wants to know.

The fenders are all the same.
