What is this car worth?

[Geoff Doctor]

I bought this audi for $300. I have since replaced the radiator and 
headliner in the interior. I now need to sell it:

1991 Audi 100
Auto
Power Everything
Sunroof
Cloth
Stock Radio
AC
Great Exterior/Interior (maroon w/beige)
129K Miles

Whats Wrong with it:
Need Blower Motor
Wiper Motor

Whats new:
Automatic Transmission
Radiator

Headliner
Muffler
Plugs, Distributer Rotor and Cap

So what do you think I can get for it?
