One of the easiest cars to strip down by far the good old imprezas,I'd love a 2/3door one,my Cossie would be long gone,loved the impreza wagon I had which never ever let me down,it even stood for years and fired up straight back into daily use with no issues at all,superb motors,yet getting a Chav rep now sadly.
Good idea that though,buy a 2dr and a 4dr and do the business,if the 2dr shells only £1000 and you can pick a 4dr/wagon up for £2000 that's a cheap car your getting.
I know the guy hasn't sold anything off his blue one that we broke but there wasn't too many nice bits on it,although mechanically it was fine,as they tend to be.
