Tony, if I fit a 5.0 V8 to my Escort to increase the fuel economy, which will thereby decrease the amount of time spent on the road as it will be in the petrol station more often, will you reflect this in my premium?

Also, I plan to fit a roll-cage and harnesses, not because I plan to do trackdays, but incase a large rock falls out of the sky and lands on my car. I trust I can enjoy a reduction in my premium to reflect this also?
