For 1958, the styling of the full-size Chevrolets was fresh and new and the cars were longer, lower, wider, and more luxurious. The trusty 283 remained the mainstay powerplant, but new for 1958 was the first of the company’s legendary big blocks. The new 348 was available in four different states of tune. Despite a weak American economy, Chevrolet’s sales remained strong, and the new high-line Impala series accounted for more than 15 per cent of sales. Chevrolet continued to dominate the low price field, with more than 1.1 million cars sold.

The Impala, a trim line of the Bel Air series for 1958, was at the very top of the Chevrolet range and was offered only in sport coupé and convertible versions. Trim features included Impala script, insignia and crossed flag emblems at the front of the cove, broad ribbed body sill panels, large dummy chrome-plated scoops ahead of the rear wheel wells, and two-spoke deep hub steering wheels with Impala medallions.

Superbly finished in Chevrolet Silver Blue over straight panels, this Bel Air Impala convertible features power steering, power brakes, the original owner’s handbook, and a Continental kit. The interior features the correct two-tone blue and grey vinyl upholstery with blue wool carpeting. Most importantly, it is equipped with the Turbo-Thrust 348 CID V-8 mated to a Turboglide transmission. The big V-8 offers effortless acceleration and will make this big convertible an ideal car for pleasurable touring.
