Hi Steve
Just a simple question to start with, eh?
Cars that can run consistant low 12s are quick cars.
Do you know what it it would run as standard? My database has a Saab 9-5 Areo 2003. 2290cc turbocharged manual 250bhp 258lb/ft weight 3510lbs, running 15.06mph/92mph. Is this your car. If not, I will need all the differences: weight, bhp/torque, tyre sizes, etc. Steve
