Based on an average of 24 mpg and petrol price of 135p a litre, would need to work out the average fuel price for super unleaded for the last 3 years really, then account for the miles done on track at about 9mpg which although not many compared to on the road might drag it down a bit, so it could be a bit less monetary wise.
I did work out that in 3 years adding up all the servicing (extra servicing too!) general maintenance, tyres, brakes etc. etc. as well as 'mods' although not many but that I'd spent nearly as much as the original purchase price of the car again!! It's probably passed that by now though...
All worth it though, despite it's foibles (read as being a French POS) I still love driving it for some reason, and so it stays
Holy Sh#t is all I can say, I've had the car from new 3 years at the end of May. In that time I've covered 66,000 miles which equates to 2750 Gallons at a cost of £16877.37.... Thats a grand more than the car cost me.
