got 1 1/18th scale, 1 1/43 and a boxed collection of about 8 that i got from the states
plus got 14 1/18th scale of various cars including a jaguar xj220, dodge viper to name a few
had mine now for just over 2 years, looked through a few car mags recently and nothing stood out as Z replacement, not that i have plans to change anytime soon
looks like a pioneer but isn't, more than likely a china rip off, almost sure they were on special offer the other week for £299.99 inc fitting

guess we've all done something similar when we were all younger, such as mucking about pretenting to be a jedi for a laugh but nowadays it's too easy to video something then spread it via the 'net for everyone's amusement
Welcome, almost, to the world of the Z
15k should get you a decent Z either import or a early uk car ( could be wrong of course )
am sure someone else will pop along shortly with proper answers
