Owner doesn't know about the Evap core and harness.

I've basically narrowed it down to a six cylinder w124 or w210.

There are a few examples of each for sale around here, and I'm likely to jump on one.

I'm scared by the evaporator and harness issues on the w124s (just the evaporator on the earlier ones).

I would guess that the early w210's have the same issue with the harness, and maybe other issues as well.

Similarly, the suspension on the wagons worries me quite a bit.

I'm wanting to stay at 4K or below, so in that range what would be best in terms of longevity and drivability?

Thanks so much, as this discussion has largely shaped what will be my next purchase!
