To me that's "Honey, I shrunk the X1/9."
Big fan of beach cars myself, especially the Mini Moke for its driving dynamics. I've got a picture of me with one I hired on holiday in Kos in the early 90's somewhere, I'll have to dig it out.
Also love the Fiat Jolly and Citroen Mehari, which you can buy the bodies and parts for from The 2CV Shop to build your own -

Hmm, I wonder what one of those would be like with a BMW R1 motor up front?
