I run a Hawkeye WRX so am used to high MPG and as stated there's no road tax to pay for me, just thought that you seemed to be getting a lot of "fun" car for the money. Over here they sell for a good few thousand more than UK prices so as long as it didn't go bang then I could probably buy one to play with for the summer and then sell it on at the same price I paid for it maybe a little bit more.
If it did go bang then I reckon there's more than £3k of salvageable parts which I could sell on then scrap the rest.
Food for thought me thinks
