jase,dont let it stress you mate.its no good.as you have said it is just a car.if you break it,it will be a shame but at the end of the day it is just a car and tania is more important.as is house buying etc.you can always come back a few years down the line if you fancy it.and in the mean time get a useable toy for less.evo etc are getting cheap now.
like i say it would be a great shame but needs must.
