2000 S4 - opinions needed

[radek at istar.ca]

Hi Gang;

My son found this car and we went last night to see it - as much as it  
is hard not to fall in love with a car like that, I'm trying to let  
the reason talk.
Basic facts:

- 288,000kms (180,000 miles);
- Stage 2+ tuned;
- AWE exhaust;
- lowered with Neuspeed springs;
- AWE SMIC's intercoolers;
- SAMCO hoses
- 034 air intake, aftermarket air filter;
- chipped ECU;
- 6 puck clutch with RS4 pressure plate;
- short shift kit.

There is pretty bad rust on the A-pillar, windsheld will have to go  
out and everything be properly cleaned.  Front door handles fall off.  
Interior is pretty decent.  Airbag light is on.  Car drives fine,  
suspension is tight.

I checked codes with VAG-COM and got three engine codes (coolant temp  
sensor, lambda sensors) and a few alarm system codes.

What should we be aware of (I'm afraid the turbos might be on their  
last legs given the mileage, timing belt coming up), and what a car  
like that should be worth?

TIA,
Radek
