well at the mo im thinking that if it is water pump and head then i would be looking at over £1000 i think....... so what i could do is take out a warranty then after 90 days i can claim on the wear and tear side of things. so if i can leave the car for 3 months then all it could cost me is £50 excess and just 20% of the parts. but 3 months without my own car will be hard.
