Nice motor
A couple of things to watch out for -
I'm sure he knows it's a pre MY04 model which has had the MY04> 17" alloys fitted (looks like the may have been refurbed as the spokes should be diamond cut). As mentioned above that means it's not got the new suspension set up so a good Geo check would be advisable.
Mention s2ki.co.uk to him if he hasn't already been there - some great hints and tips and the new owner guide is a must read - especially the part re protecting the roof - a small investment of £8.00 for a couple of neoprene chain guards for the roof mechanism elbow joints can save a very expensive roof repair!
As for the driving experience - I would agree with the above - not quite as involved as an Elise and doesn't inspire the same confidence in handling straight away. However once you learn how to work the gearbox/engine and get used to the passive RWS it is a joy to drive. In may ways the VTEC helps the way I use the car as it is a daily commuter as well as a weekend toy - so has a dual personality. In the wet - take it easy and use the "push to pass" revs carefully! Driven smoothly though it is still a good drive in damp conditions.
Oh yes - one more thing - oil - keep a top up in the boot and a nice wee funnel - it WILL be needed!
Cheers
