I absolutely love the classic (IMO) Mitzi Ralliart Tommi Makinen Evo VI (footage of TM driving one), however regardless of the fact one is now within reach I just couldn't bring myself to drive one around.
Shin you just have to accept that for all the things that are superb about your STi people will mostly judge it by how it looks. If you're of the opinion its a cool car to be seen in you really should take stock.
I'm a little obsessed with the Audi Quattro S1 but again I'd look like a silly billy driving one around. Plus a decent one is likely to set you back more than £35K so no hope for me.
