Hello, love my cars thought I'd swap one of mine for this, no idea what model it is, if someone could let me know what it is and possibly how much it's worth.
Would be appreciated,
Thanks.

GP Superbuggy MK1 with a modified rear end is my best guess

As above with later side panels fitted. Value is hard from photos  3 to 5k is a ball perk figure

Cracking thank you.

What they say basically. It's a MkI GP Superbuggy with a modified rear fitted with 'Alpine' side pods/scoops from a MkII.
