I'm in the Woking area too... I generally don't wave at Celica's anymore as there are such a variety of owners, ranging from guys like yourself to older women, and the good majority of the time ya just end up looking like a dildo . I wave a other ST205's though as they are a lot more rare compared to other Celica's and is like being in a bit more of an exclusive club lol.
I'll keep an eye out for a lagoon blue Gen 7 ... My car = Storm Grey ST205 with TRD kit, bronze alloys and a black WRC spoiler being held together by duct tape lol!
