hey Glenn, welcome to the clan
that RS5 sounds like a hell of a motor.
I saw a car the other day with what looked like a motorcycle security chain through the wheels front to back with a blood big padlock.
A bit over the top & a bit messy to put on/off but I suppose when you have an expensive sporty car that's an option.
happy motoring
greetings dan
welcome to the clan.
As Steve says, make sure the engine is not knackered before spending money on it; mind you, when you mod the ECU it makes a hell of a difference, good fun.
happy motoring
