Yeah, against tampering with any "functionality" of the car. Definitely won't go there. Exhaust oil smoke is the go... That'll be enough to send him into overdrive.
Last time in Jamieson his Ctek solenoid was stuck shut and drained both his batteries, and then when his car didn't start he nearly took a week off on stress leave. Loves is shit lux! So the smoke thing will be a direct hit !! lol
