knocker

Hi all ! I have had my C3 VTR for a few months now - and I'm thinking of spending some money on it - as it's summer and all. If anyone can give me advice on the options I'm thinking of I'd be grateful ! Especially a rough ide of cost :P Tinted Windows. Not cos I want to look like a propa gangsta - but the C3 bless it, feels like I'm driving a greenhouse on sunny days. Been given a quote of about £300 for this. remapping/chips dunno if this would really offer much better performance - and will probably wait unntil after my first big service anyway. ICE The sound in my car is lacking - especially when the diesel is in full effect :( I would like to uprate the speakers, get some kind of bass in the car and perhaps plug in my ipod. Lowering The suspension is firm enough - but the car is soooooo tall. I could do with losing a couple of inches ;) all newbie questions - but that's ok - cos I am a newbie.
