Just remember that it is a modified car, so there are days when it isn't quite behaving, or there's a rattle or it's really cold and you have to use a lot of throttle to start the bloody thing - this is when I think "sod it, I'm selling up for an SUV and a pair of comfortable slippers."
…Then you drive it and remember why you did this, with a massive smile!
Plus, how the hell do you even sell a car this modified?
Erm....you don't sell Dom just keep it and buy something else
You could never pull back the money spent on mods unless you get some real enthusiast willing to pay extra and the work and problems encountered already sorted on a completed car
