Also saw a Fiat 124 Spider Abarth (the new Miata based one). First one of those I've seen. Black with red decals, grey interior with Abarth logo headrests and steering wheel, quad tip dual exhaust. Looked GREAT, although I would never buy a black convertible. Any black car for that matter, they're too hard to keep clean.
Saw what was probably a '65 Shelby GT350 clone. Didn't have the Plexiglas sail panel windows, just the metal "vents". White with blue stripes. Automatic trans (giveaway, since I don't think they were making autotragics that early in the non Hertz rent-a-racer models).
And I saw a Civic Type R, for the first time. Black with red, a little too boy racer for me. The red just highlighted the wings, gills and strakes. Interior was bright red. All a little too over the top for me.
Other notable car I spotted was a new Toyota CH-R. Not really special, just Toyota's answer to the Honda Fit.
No, I believe you were probably looking at a genuine GT350 there. If Shelby ever had a Plexiglas pane in a '65, it would have been on a dedicated track car that had several other modifications made to it. All '65 production Mustangs (including Shelby's) had the normal split side windows. By '69 Ford dropped the split and installed the dreaded one-piece on cars... trucks kept them for awhile.
You're probably right. The '66's I've seen have Plexiglas windows, and just ass-you-and-me'd that all the first gen ones did.
Tributes I've seen built on a regular fastback still had the vent windows.
Recently saw an auction for transitional models (252 or something). Ford wanted GT350's in the showrooms at the same time as the new model year Mustang. Shelby couldn't have waited for Ford to send them production models, modified them and delivered them to showrooms in time, so Ford sent him a quantity of 65's that he worked his magic on.
Built to 1966 GT350 specs they had a Plexiglas window in place of the metal vent panel.
