WHy bothere though get a diesel for cheap road fund any anyway insurance is down to loads of cfactory price to fix engine size doesn't always have an impact. Thats why it can be cheaper to insure a group 12 car with a 18 engine than a group 9 car with a 1.6 engine sometimes as the group 9 car may be famous for crashes and expensive claims.avance70 said:well i bet if something similar was to be done to a 1.2 engine, one could get a fine amount of bhps, while keeping the insurance/registration costs quite low...
