The off-again/on-again rear fender skirts were gone again for 1964. Otherwise, this year’s Fleetwood Eldorado convertible looked very much like the ’63 Biarritz. Price went up by a paltry $22, but performance went up in a big way as both bore and stroke were increased (to 4.13 x 4.00 inches) for 429 cid and 340 bhp. A significant development was the arrival of GM’s new Turbo-Hydramatic transmission.
