Just picked up this 10/1983 323i. Even on the test drive it was obvious how much more grunt the 2.3 had.
Only real problems were cosmetic; paint needs a buff and polish, seats are torn(I have my Suzuki GTI's anyway), shifter boot is made of insulation tape and all 3 pedals felt a bit funny. Clutch had zero feel, brakes were super stiff and the accelerator pedal was sloppy. I should be able to sort it out with all the E30's I now have though.
Klaus may be up for sale soon.
A svensational photoshop.
