I voted for suspension too mate -- I've got KYB's and RSR springs on my Glanza mate, I'll let you feel how stiff they are at Brunters... For me that's the next sensible step, then wheels, then music. I've got my girl's old stereo in my car... it doesn't get the radio because I need an adaptor for the ariel and it doesn't feed the rear speakers because I need an adaptor for them too... but it plays my CD's so I'm not too bothered!
