The seller does not detail what is needed to make the car 100%. Classic 900s can be converted to the infinitely tune-able T5 engine management found on newer Saab 9000s. I got a ride in a converted car and it had none of the turbo lag these cars are legendary for. The biggest downside to any modified classic 900 is the fragile 5 speed gearbox. Manual gearboxes are a consumable item on even a stock 900 turbo.
