Welcome you dirty 'ol lovedog!
How is the ride on the 18"s? I'm also getting a (left-hand drive) 1.8 i-
Vtec Sport soon (although the "Sport" designation in mainland Europe seems to be a mix of the UK's Sport/ES models). And, in Alabaster Silver too! So good choice there!
I've specified mine with 17" rims as I thought 18"s might make the ride too hard and the handling a bit skittish. Hence, it'll be good to get your views, seeing as you've had the car for 3 months.
