Thanks for all the comments chaps.
I have a lot of plans but all are subject to change. I can confirm some will be interior or exterior cosmetic mods, but mostly I'll be working on the engine, suspension and drivetrain I suppose.
I've made a couple of purchases already, so once they become 'mods' I will make sure to post the outcome.
Dave although the car is highline, I'm fairly sure it's a bog standard stereo. It's certainly got no tweeters in the door etc - just the usual 4 crap speakers and 2 subs under seats. It's the only option I really would have liked to hang on for.
