I realize SVZ’s should probably be grouped with Sprints and Sprint Veloce’s, but the hand of Zagato and the hefty price tags makes me think they are better grouped with SZ’s.  There are never many of either changing hands, likely the result of there being 250 or so of both models combined potentially existing world-wide.  There do seem to always be a few changing hands every year -and a few more on offer as evidenced in this post.  I still think a late Coda Tronca SZ is my ultimate Giulietta. 
Market 418 was SZ 10126*00051, a nice one that sold at auction in Monaco for $340,000.
Market 379 was this Sprint Zagato Coda Tronca -one of a very few made, and whose number I never caught, with an asking price of 270,000 Euro’s -about $356,000.
Market 380 was an unidentified Sprint Zagato with a 300,000 Euro asking price – about $396,000.
Market 384 was Sprint Veloce Zagato 750 E 1493* 06184, a stunning example of a SVZ, selling for 414,400 Euro’s – about $546,000!
I sold Chassis No 00216 last year it was the next to last SZ produced , It had European racing history and went to France ! I replaced it with a ’58 SV fitted with a GTA close ratio box, a ZF limited slip rear and a two liter engine… It goes quite well and is a worthy substitution. Happy new year. Frank Allocca
