Hmmm, looks in nicer condition than mine. I'm eyeing it...
They've pretty cool engineering for the early 70's - inboard vented discs, FWD of course hence the forward engine and slanted. Radiator fan is belt driven from engine. Rear beam design carried through to many Audi/VW since.
They're a deceptively big car being based on the 100 rather than the 80 like the Coupe GT. Real cruisy & comfortable but brisk as a manual and great handling for their time.
