just an update on my z3.
i got the door handles back on the door panels with some epoxy and a few screws. I put some grease on the window tracks and now the windows are working again. I also replaced the exterior door handle gaskets and got the passenger side exterior door handle to work.
then i cleaned the door panels with a magic eraser and conditioned the door panel leather (high quality leather I might add) with leatherique.
next i changed the differential fluid and replaced the missing driver side wheel well liner.
then i changed out the suspension including the lower control arms and bushings. I put on bilstein "touring" struts up front with the stock springs and kyb shocks in the back with the stock springs. i also added a Dinan front strut tower brace. car rides great.
now i need to investigate the transmission warning light, abs light, glovebox sag, put in new 5.25" speakers in the kick panels (pioneer), and strengthen the cracked dead pedal by putting in a metal one.
