By 1966, the performance brigade of big bruisers were rapidly losing ground to intermediate muscle machines and pony cars. Oldsmobile would send the Starfire into orbit one last time. The Impala SS started its rapid descent from its peak.
The Galaxie XL gained 7 Litres of might to fight for space as it was crowded out by the LTD, Thunderbird and Mustang over in Dearborn.

As the 2nd half of the 1960’s got underway, Cadillac found itself not doing much wrong. The most premium General Motors offering had long banished American luxury rivals to the lower rungs of the sales charts, if not into the grave.
