OK then, here's my personal response, others may have differing (wrong) opinions:
I'll want to tinker. I'll give it more boosts, it'll blow up. I'll sink a fortune into repairing it and, while I'm at it, have a few more boosts installed. It'll blow up again and I'll spend another small fortune whilst lying to MrsREV about where the car is and why our bank account is empty again. Then I'll stop driving it because I'll be scared it'll blow up again. Rinse and repeat until I throw my toys out the pram and buy a diesel Golf.
I want a toy, not a grenade with the pin pulled.
The politics of failure have failed. We must make them work again.
