I don't think there is any year to avoid in the 129 series, as they are all terrific. But I think you should make a point of comparing a 1996 or newer car with an older model. The newer cars have the 5-speed electronically controlled tranny which seems to make them considerably more refined. And if you do finally get an older car with the 4-speed tranny, consider getting a modification kit from Bergwerks to make the car start-out from rest in 1st gear instead of 2nd. Finally, unless you just can't do without the extra performance, don't overlook the six-cylinder 300SL and SL320 models.
