I'm 36 and pay £500 per year for mine.
We still have the AP2 designation in the UK for the facelift but we didn't get the 2.2 engine like the USDM
There was never an AP2 designation for the UK. They are all AP1 but are referred to as "facelift AP1". It's a common mistake and understandable as even Honda dealers refer to them as AP2 sometimes.
Also believe they moved from a throttle cable to an electronic throttle on later cars but no idea how much difference that makes to the drive.
2006 and it makes no difference.
The later cars are softer and less prone to swapping ends in the hands of idiots. Some don't like this (me included) so have the earlier model year geometry setup to get back the pointyness.
I would buy on condition and history rather than age. I prefer the look of the facelift so my preference would be to go for a 2004 to 2007 model. 2008 - 2009 models have had reports of engine issues with some guys in the owners club covering less than 20k miles before needing a new motor. The general consensus is that the newest S2000 you should buy is a 2007.
You want a FSH preferably from a specialist rather than Honda. Honda don't know how to look after these cars and frequently miss service items that are unique to the S2000.
WHatever you buy, make sure you get proof that the geometry is correct and that the geo bolts have been greased. If they can't provide proof, INSIST that the geo is done and the bolts greased as part of the condition of sale. Seized bolts can present you with a £1k bill to have them replaced so this is vital.
