The warranty on my Altis 1.6E is about to run out, amazingly it's been three years. It's got 46,000+ on the odometer.

How do I fix it up? What I mean is, what options do I have from the most simple - like adding sideskirts, modifying the front and rear bumpers, halogen bulbs for the headlights and fog-lights, dressing it up with a good set of shoes...

to the extreme like having an engine-swap, modifying the exhaust system, putting in a blaupunkt sound system, and the like...

I'm a complete newbie in this so I need a helping hand for the most practical upgrade which can achieve maximum impact.

How much are all the possible options going to cost? I'm not interested in making it look too riceboy-like, I don't want to compromise the ride quality too much (i.e. lowering the suspension, 19" rims, etc.). I don't care too much about spoilers (who needs them if you don't plan to go above 180?).

Thanks!
