Here I have a 1998 z3m roadster with the s52 motor that also come in the e36 m3.
Not perfect by any means but does run and drive.
New radiator, upper rad hose, lower rad hose, some other coolant hoses, rear upper shock mounts, clutch master cylinder, braided steel clutch line, fuel pump, Dinan red coil packs, new spark plugs. I’m getting the center console trim 3d printed so that will be replaced soon.
Could use the following: suspension, u joint for driveshaft, and rear subframe reinforcement (4 spot welds in the trunk are popped), paint, a hard top or a new soft top, weather seals for soft top ( little leak but I try my best to keep it dry), some interior stuff, most likely needs a MAF ( it has p0101 code but no vacuum leaks).
Will consider trades for other 6cyl bmws like e36 or e46 that are in decent shape. ( can add cash if needed) also interested in other manual RWD cars. 8500 obo
