CArl,
I didn't realize you were in the UK.
The yellow one at PIM looks well executed, but will not appreciate like I believe the true GT5's will in future.
You can always put out a request for someone in the LA area to inspect it for you. I've done inspections in my local are for prospective buyers. I have nothing against the folks at PI Motorsports but they are consignors and do not warrant the cars they broker, so due diligence is required.
If you want an original GT5, it appears this might be up for sale soon;
