The Corvette's first major restyling since 1963 occurred in 1968.
As the sales brochure read, "Corvette '68... all different all over"
The fast-back was replaced by a tunneled-roof coupe.
It featured a removable back window and a two-piece detachable roof section or T-top.
The convertible's optional hardtop had a glass rear window.
The front end was more aerodynamic than those on previous Corvettes.
As before, the headlights were hidden.
Now they were vacuum-operated, rather than electrical.
The wipers also disappeared when not in use.
Except for the rocker panels, the sides were devoid of chrome.
Conventional door handles were eliminated and in their place were push buttons.
The blunt rear deck contained four round taillights with the word Corvette printed in chrome in the space between them.
The wraparound, wing-like rear bumper and license plate holder treatment resembled that used on the 1967 models.
Buyers had their choice of 10 exterior colors
- Tuxedo Black
- Polar White
- Corvette Bronze
- LeMans Blue
- International Blue
- Cordovan Maroon
- Rally Red
- Silverstone Silver
- British Green
- Safari Yellow
All convertibles came with a choice of Black, White or Beige soft tops.
Interior colors were
- Black
- Red
- Medium Blue
- Dark Blue
- Dark Orange
- Tobacco
- Gunmetal
