You will find everything you need to know on cliosport.net
I owned a 172 for over 3 years and that website was very helpful as well as a great social site.
Not much i can say that hasn’t already been said but a standard 182 is quite undesireable, everyone wants the 182 with cup pack (factory upgraded suspension and wheels)
Cam belt is done every 72k or 5 years and as already said by others will cost a lot of money, around £1000 at a main dealers but slightly cheaper at a decent garage if you can find one.
There is no doubt that they are quick but be warned that they are NOT a Civic type R, Astra VXR, Leon Cupra slayer as some would have you believe.
Summary;

Cheap
Quick (but not that quick)
Economical
