Saw a nice metallic blue '98 A4 2.0 Quattro in Clifton in Dec, had 18s and all, "AA" number.
Black '03 TT Coupe (225) at Capital Cars, Islamabad.
German embassy Islamabad has a black '99ish bullet-proof A8 4.2 Quattro Long (used to be ambassador's car)
Older Audis...much harder...but:
1) If you go to "Perfect Autos" in Saddar, Karachi, the owner always has his 1977/78 Audi 80 saloon in beige parked outside. Immaculate shape, but then again his shop sells only VW & Audi spares;
2) Saw a very rare late '80s Audi 200 Sedan (V8 Quattro, LHD) in black sitting in a workshop dusty and rusty in Islamabad in 2000/01, no idea where it is now.
3) Spanish embassy in Isb has a '89/'90 80 Sedan in white
4) Malaysian embassy in Isb has an early '80s 100 Sedan in black.
