UK Z32s start RGZ32. As for imports I think that's JDM specific the above quote, for instance they didn't sell anything other than a turbo lwb here did they?? So for Croeso's car JN10 - no idea R - UK ? GZ32 - Z32, LWB, non turbo (however being UK doesn't it mean it's turbo by default? can't remember if your car was a turbo Croeso mate?) U001110 - presumably build date comes from this?
