price of catalytic converter for a w210 from merc? Any good aftermarket ones? I've seen this fairly good w210 e220 cdi online with 216,000km on the odo, about 4000 gbp (from Indian rupees) and i'm guessing this has been changed, and the guy says that the vehicle's never been tampered and i'm hopeful that he has the car well maintained, since he's a politician... and politicians are rich. But I want to replace it just in case. BTW, any aftermarket ones, just as good and less expensive?
