1 - 1964-66 Thunderbird
Numero Uno - I rate this the best interior design on any car, in any era. Cockpit inspired toggle switches, sci-fi inspired dials housed in silver spheres, sweeping console, cocktail lounge seating - especially in the rear. And if a '66 buyer chose the optional overhead console, it got even better. Power window switches in a center console stylishly integrated in to the overall design - the only minor criticism is the gear selector located on the column rather than the console. Otherwise - perfection.
2 - 1963-65 Buick Riviera
A close second to the mid 60s T-birds. Lots of glistening chrome, a sweeping, steeply angled centre console in (optional) woodgrain and beautifully integrated switchgear and stereo controls. And it goes one better on the T-bird in having the gear selector mounted in the console. Tasteful upholstery designs and colours round out one of the great interiors.
3 - 1966/7 Dodge Charger
The later Chargers had better looks on the outside, but this one - the first - has by far the best interior. Superb full length console that separates both front and rear bucket seats. That makers four buckets, and the rears folded flat to offer a truly enormous load area long enough to slide your Malibu in through the boot. The seats themselves were tastefully pleated but best of all was that chromed, electro-luminescent panel with full instrumentation.
4 - C1 Corvette (series II)
It was a slow downhill slide for the instrument panels of Corvettes following the beautifully sculpted dashboard and instruments of the late model C1's from 1958-1962. Sure, the C2's were nice, but not as nice, and the C3 was slightly less so again. With the late C1's - take a look at the way the speedo wraps around the tacho - race inspired, super cool, and rarely if ever bettered. The twin cowled cockpit style dash, bullet proof switchgear, and a stick-shift poking out of a nicely integrated console all added to a great driving experience.
5 - 1965 Pontiac 2+2
Woodgrain, chrome, stick-shift in the console, gauges everywhere, acres of room, ultra cool upholstery and enough room for 5 to stretch their arms all at once - big cars don't come much cooler on the inside than the potent '65 2+2. Having a mighty 421 under the bonnet doesn't hurt either.
In the 1960s Pontiac stole every European name they could get their hands on - Grand Prix, GTO, Le Mans, Parisienne - and 2+2. In Europe a 2+2 was a small sports car with a couple of extra seats squeezed in to the back (the +2). Not so Pontiac - this dreadnought could comfortably seat 6 if a buyer went for a column shift. But then, the Pontiac boys never did care much about tradition.
