I phoned around to find prices for a rear box for a 320 cdi and the only one I could find was the merc dealer at £251.97 + vat, 2 years warranty but if I fit it myself they are not sure if it would still be covered. I tried all the usual suspects like Kwik-fit, Partco, National tyres etc but nobody seems to list it. Anybody out there got any ideas. AA
