I must get it valued actually

One of my mates has a cav turbo. Bloody quick and very in my opinion. Shame they made them with a 70/30 torque split though. My mates is running around about 240bhp and kicks my S1's ass. Then again my S1 is only putting out about 170bhp

It up to you mate. Depends what you want from the car. A S1 is alot cheaper to run and modify. Cav's cool and quick as standard but expensive to uprate and the 4x4 can be very expensive when it goes wrong. Totally your choice, both cool cars
