I've heard a few people ask this elsewhere and I'm experiencing the same
thing. Passengers opening the front passenger door to get in and out find
it hard to open. I tried spraying WD-40 in the opened handle but it didn't
fix it permanently. Any BTDT? My car is a 1994 90CS Quattro Sport but I
know at least a guy with a 100S with a broken door that has advanced stages
of what I'm experiencing.
