DONT DO IT!!!!! Mind you if you get a 130 or 150 thats not so bad. I do about 70 miles a day to and from work and its not ideal but that costs me about ?150-170 per month (around 2k miles per month). Admittedly a diesel will be far better, but that is dual carrriageway driving with lots of hold ups at either end. Mind you as the boss doesnt contribute I do tend to stick around the 65 to 70mph range.....apart from the weekends!! Stick with the Mk3 as it sounds mint.
