well to put in perspective, i have a standard cvh 1.6i in the cab and i average 10p a mile fuel,

so id say to be fair on an rst, looking about 13p cos of the extra load the turbo adds,
on a 2ltr cossy allow 16p then u got wear n tear,

again cvh is cheaper by far, alot of the rst parts are same on all cvh, cossy tend to be unique to the car!!! so allow ariund 15% extra on ure standard car, then insurance just get a quote from tesco or summit for ure current car and aother for rst and cossy then u get an idea of the extra!!!!


just a matter of doin ure homework m8
