I got my 6-er in April 2004, owner stated that it is "all original" and it was, including thrust arm bushings from '86.

Picture of the car for sale in autotrader:

Car was bought as a summer/project car. It will take some time, money and effort to bring it to the shape I'd like.

Since then some upgrades were made:
- PG Polyurethane upper control arms bushings ;
- CIBIE's CSR headlights and 88-89 model turn signal lenses;
- AUDI GT Oil Pressure, Oil Temperature and Voltmeter VDO gauges;
- 3.73 LSD;
- Keyless entry;
- Miller Performance MAF system and chip;
- MOMO Fighter steering wheel
- Suspension Techniques springs with Bilstein Sport shocks;
- e34 M5 brakes with SS lines;
- Alpine 9831 head unit with upgraded 6x9 Pioneer TS-G950M and 4x6 Pioneer TS-A4670R speakers;
- Autosolutions short shifter;
- Formula One 28% tint;

And, recently: US to Euro bumper conversion (page 3)
