I would make sure its the 134bhp model available from late 2003 i believe.
I had the 2004 SVE which is a great tow car. Kerb weight 1650 kg.
While i had the inter cooler replaced, the car is still on its original turbo. My son still runs it.
You must make sure the boost sensor has been replaced under recall, or the ECU reprogrammed, or both, i just had the sensor replaced.
If you go for the 112bhp? model, these had some issues with injectors, look for black smoke from the exhaust.
And rattly time chains, due usually to the chain tensioner failing i believe.
Note both engines sound very noisy when first started up, this is normal.
