Assuming the tyres are in good condition and the geo is correctly then it shouldn't be any more trouble than an equivalent RWD car. Some cars will have VSC to help out, but if you get one with it it can be turned off
VSA is available on 06+ cars with drive by wire throttle but beware that it'll cos you over £400 a year on tax (£215 on <55) and mods are much harder to get hold of for DBW and there are currently no ECU mods at all for them. This is because the F20C was changed to an F22C for the US and JDM market which is a 2.2 with a silghtly different bore and stroke iirc. Hence no current ECU upgades.
First thing to do when you get one is get it booked in with Chris at Centre Gravity if you're anywhere near the midlands as the geo is the lifeblood of whether you'll love its handling; or hate it because you found a ditch! If you buy from a dealer get it in writing that they will check ALL geo bolts for seizure and fix any that need doing otherwise come geo check time you may find yourself with a bill of £600 per side for new arms as the bushes aren't changable.
Also when buying check the hood for wear. Look at where the hood base meets the body near the driver and passenger windows as it rips there and also check inside above the driver's right/passenger's left shoulder as the hood mechanism wears through creating a hole (which is what I currently have on my 04 plate).
Main changes to the car in its life are as follows:
<03 has firmer suspension with slightly thicker ARB's and 16" wheels, known to be a little more snappy on the handling (especially the <00 models). Some cosmetic changes took place such as a cover for the drivetrain on 01+ and a glass rear screen on the hood from 02.
The 04+ had a revision of the damping and ARB's to reduce the risk of snap oversteer, also coming with the 17" alloys, revised front and rear bumpers, revised exhaust styling to oval exit pipes, new interior consoles with brushed ally effect and new paint colours.
06+ had DBW and VSA fitted as well as further damping and ARB changes to put it between the <03 and 04+ models making handling slightly firmer again but thats all I can think of for the time being.
Hope that helps
