Hi whistler , the one I'm going for has 84000 mls full history in mica red just to be different , I think 100 k is ok if the car is in good condition and been serviced properly, low miles is not always good, acids in the engine when a car does not get up to temperature can cause damage ie school runs of less than 5 mls is not very good, at least with high ish miles you know the car has been used for motorway work (you could not get very high miles any other roads ! ) my is200 has 96000 mls and runs sweet as a nut , uses not a drop of oil between services, different engine I know but serviced regularly modern engines can achieve big miles, good luck in your quest for a 250 , keep us posted,
allan
