Looks like a 1963 Fleetwood 60 Special to me.
Yep, Chapter Member Chris Wielusiewicz' 1963 Fleetwood 60 Special.
Could be the 63 Sedan DeVille 4 window that was on the sight very recently
Truely in drop dead condition ( that’s real good !)
Just to add regarding this car from above:
If you click to enlarge, the things that give it away include the vent window on the rear door, the c-pillar louvers, and rear window reveal trim. Dig a little deeper and you will notice the chrome trim on the ends of the rear qtr panels. There is also no side trim protruding but it is debatable how well it would be seen from this angle. It has the Guidematic phototube on the dash which was standard on 63, but moved to the LH fender tip in 64, but would have been on the dash in 64 if dealer installed. The car also has the factory installed cruise and dealer installed RH mirror and door guards but that really doesn't point out the body style as both were options on other body styles. There is a V on the hood which would be correct for a 63 Fleetwood but not a 64 Fleetwood as it picked up the wreath. I guess the most telling thing for me is the wider fatter 63 rear bumper end ... the 64 is quite thin compared to the 63. Anyway, look for a full feature on this car in our June 1963/64 Cadillac Chapter Newsletter.
63 series 60 Special.
