The driver's seat in my car is getting pretty bad, I think it's past the point where any more McGuyvering is worth it. My dad has welded stuff to it, we've restuffed it a few times, it may be time to let it go.

What range of years/models would fit in my car? My mechanic has a W124 300D 2.5 turbo he's gutted for engine stuff, would those seats fit in my car?
