I am now thinking of upgrading from an'A' to a proper Merc. Can I have some advice from members as to which of the above is the most economic and does the 'Auto'in the case of the 220 have a five speed box. i would welcome all and any comments on these two marques and tips for which is the considered best. From my own research I would hazard that 97-99 250TD appear more solid but I await advice and tips on what to look for and what level of mileage with full service is acceptable. Caution leans me to models with 60,000 - 80,000,am I far to cautious. Thanks.
