Sankar is right -- 1966 1500 Fiat Spider. This one has the 1500 (a Lampredi designed crossflow OHC ~80 bhp engine) replaced with a 1600 (or 1800 -- have not ID'd fully) Lampredi designed twin cam engine from an early 124 spider/coupe. The sound is just awesome.
ajmat -- yes, you'll see it tomorrow.
