I ended up giving my Bburago F40 to a neighbor kid, hoping to start his collection. I never had the Bburago GTO, as I received the 1:16 Polistil as a gift, but eventually upgraded to the base HW & then the KK.

My first 1:18 was Corgi's Lotus 72 sometime in the '70s, but Bburago's Jag SS100 really got me started in the early '80's. Still have that one, though haven't taken any pics.
