For all the work you have done to this car, it should be in top shape. last thing I remember is you doing the rear suspention.
well to give you some confidence, we take our 80 240D on some long trips. we have been to Portland, Or. 3 times this year, and it is about 730mi one way. one trip to los Angeles, about 400 one way. been to Carson City, Nv. twice, about 280 one way, and we have to climb over the Sierra Nevada mt. range, and going over Hwy 50 gets up to 7400ft, then down through Lake Tahoe. we have that trip coming up the end of the month.
we now have 327K on it, and the car was given to us by the original owner year ago last Feb, with 306K.
Maybe take one of your 240`s.

as they say, they are bullet proof.
