Quick list of problems off the top of my head
Dodgy paint finishes on satin silver
Nighthawk black is a b*tch to keep clean
Extracting extra power is expensive
Faulty headlight motors
2nd gear is hard to slot home when the gearbox is new
Alloys corrode
Rear tyres "feather" on the insides due to poor factory alignment
Exhaust manifold heatshield rattles
Facelifts have poorly sealed windscreens
Fuel consumption around town is poor
Headlights can get condensation in them
Paint is thin so suffer from stone chips easily
VTEC likes to eat oil at the rate of about a litre per 1000 miles
Little blue lights in the rear view mirror indicate you are about to lose your license
Despite all that, and most of the above will be fixed under warranty, I love mine to bits.
Changes to the facelift models - roughly 1500 changes, however the main ones are:
Lighter flywheel.
Additional sound deadening.
Different front and rear light clusters.
Different front bumper.
Red door inserts and red inserts on the seats.
Indicators moved to the mirrors
If you fancy something a little different see if you can source a JDM spec car in gorgeous white. They have more power due to better cams, intake and exhaust manifolds, valves, springs, smaller cat, HID's - and more importantly - an LSD. They are group 20 insurance though, but there's probably no more than 10 or 15 in the UK.
