1st car, Fiat punto, bog standard, 1l. 55bhp on a provisional license wasjust over £700. and for passing I had to pay £1458.98 so basically doubled. after a year it halfed, got a new car. a 1.4 16v VWlupo. modded. and mods declared. (new alloys. lowered, debadged, engine remap) didnt change. changed to an Astra 1.4 estate went up £13 a month so I think it goes on car size rather than engine size. Oh and it didnt change when i told em i had points!
