I wouldnt have even let RAC take it to their workshop.
I would have got it towed stright to prefered workshop.
but at this stage mate for the price of a tow truck
get it taken somewhere else.

Seriously it could be as simple as the radiator. They could fix that test your engine and say your fine. Dont take rac's word on it. Just becuase their little meter detected CO doesnt mean it is. And even if they are corrrect Id still rather a known workshop do the work.

Which Rac building did it goto. If it was Osborne park then its about 500meters down the road to west racing.

Do your wallet and ya self the favour dude and get it down the road.
