I havent seen any listed or sold on eBay, i picked it up a couple weeks ago becasue of how bizarre the cart looked. Is this variant any mre valuable than they regular silver cart that you see everywhere? Those handle holes on the back make it look so goofy

It's the UK/Codemasters version of the game, rather than the North American/Camerica version.

Might be of interest to some Euro unlicensed collectors.

Thanks for the information, I'm probably gonna hold onto it since its such a weird looking cart but its good to know in case i ever did want to get rid of it
 

Can confirm, this is what my copy looks like, PAL version. I've got Micro Machines and Quattro Sports in the same style too!
