The 4th generation Impala, sold from 1965 to 1970, was a massive success for Chevrolet. A 1965 redesign introduced a new full-perimeter frame and curved side glass, and it set an industry sales record with over 1 million cars sold that year. Body styles included coupes, convertibles, sedans, and wagons, with engine choices ranging from economical inline-6s to powerful big-block V8s like the 396 and 427.
Collectors prize the '65-'70 models for their classic styling and the wide variety of configurations. The 2-door hardtop is the most popular body style, and Super Sport (SS) models with big-block engines are the most desirable. Convertibles also command a premium. More recently, the '67 4-door hardtop has gained a cult following due to its prominent role in the TV series "Supernatural," boosting interest in a previously overlooked body style.
The market for these Impalas is very broad. The average price of around $27,000 is skewed by the large number of driver-quality small-block cars that trade hands. At the top end, numbers-matching SS 396 or SS 427 cars, especially convertibles, can bring significant money. At the other end, 4-door sedans and wagons remain an affordable entry into the classic car world.
Buying Tips
- Check for rust thoroughly. Common areas include the trunk floor, rear window channels, lower fenders, and the frame, particularly around the rear suspension.
- Decode the VIN and cowl tag to verify the car is a genuine SS model. Many clones exist, so confirming the original engine, paint, and trim is critical for valuation.
- Big-block cars, especially the L72 427, command the highest prices. Verify engine block casting numbers to ensure it's not a more common small-block or a later-swapped engine.
- On convertibles, inspect the condition of the fabric top, the hydraulic pump, and the weatherstripping for leaks and proper operation as repairs can be costly.
- Suspension and steering components are common wear items. Check for worn ball joints, tie rods, and sagging coil springs, which are frequent on these heavy cars.
Prices for 4th generation Impalas range from as little as $800 for project cars to over $80,000 for pristine big-block convertibles.
