Guys, we need to realise that all 4200 derivatives are weak residual cars and very few people in the trade will touch them. Try this out by looking at a 911, AM, M series BMW etc and suggesting your 4200/GS as a px. Most dealers will not want it. Also look at how many 4200/GSs are not selling and are dropping in price. Remember as well that mileage kills these cars values.
We also need to be less critical of cars advertised for sale. Personally I have never seen a car more than a year old that could pass for new and these cars are all 5-8 years old now and will, of course, have some element of wear. As for service history, the Maserati recommended change dates are very conservative and, as I posted on the other forum, there will be no 4200/GS that has a full service history. For example, how many of you change the auxillary belt every three years and the lambda sensors every four years?
The more we find holes in cars for sale, the more we destroy our cars values and their reputations.
