This is a 1968 Chevrolet Impala SS Sport Coupe with a desirable and powerful 427 under the hood. This year saw a change to the SS, rather than a separate series, in '68 the SS was once again returned to an optional equipment package and certainly wasn't quite as distinctive as it had been in previous years.
The Sport Coupe had a pronounced sloping roofline although this year also saw the launch of another 2-door, the Custom Coupe which had a formal (notchback) roofline taken from the Caprice.
Continuing with the tradition, Impala still had triple taillights on each side rather than a dual configuration found in the Biscayne and Bel Air.
The SS package included all-vinyl bucket seats and center console. It also included Console shift, SS wheel covers and various body and interior trim.
Primary competition for the Impala would have been from cars like Dodge's Polara, the Plymouth Fury and Ford's Custom, Galaxie and LTD.
Power comes from a 427 cubic inch Turbo-Jet V8 (L36) producing 385 horsepower. It's mounted to a Turbo Hydra-Matic automatic transmission a combination that was a $290 option at the time (if purchased with the SS package).
All full-size Chevrolets had a wheelbase of 119", overall length of 214.7" and 79.6" wide.
Chevrolet made 710,900 Impalas for the 1968 model year and it was actually their best selling full-size car for this year. The 2-door Sport Coupe had a base price of $2,863 for the base six cylinder and a further $105 for the V8. The SS package came in at an extra $179.05. The options on this car makes it one of 1778 made.
