1963 Chevrolet Impala hardtop with a 454 and TH400, early bid well under driver comps

Why we picked it

Why we picked it: this 1963 Impala two-door hardtop has a 454 big-block, a TH400 automatic, power front disc brakes, an aluminum radiator and stainless dual exhaust. It has a clean Pennsylvania title in the seller's name, and the seller has owned it since 2018. The VIN decodes as a regular V8 Impala, not an SS, so it is a driver-grade cruiser rather than a collector car.

The bid is $12,250 with nine days to go, while comparable driver Impalas have been changing hands for $20,000 to $34,000. Bids usually climb near the close and the reserve status is not shown, but the drivetrain and brake work already done make it a good base for a big-block cruiser build.

The value check

The current bid is $13,910. Comparable cars in the same condition have sold for $20,598–$34,352, so the middle of the market is about $27,475. That put this car 49% under. Bids usually climb in the final hours, so the discount will likely shrink.

Driver-grade 1963-64 Impala hardtops on Hagerty Marketplace went for $20,598 and $32,100 in 2026 (fees included), and a 1963 drew a $34,352 high bid in October 2026. The $12,250 bid plus the 7% buyer's fee is about $13,110, roughly 52% under the $27,475 midpoint.

Where the numbers come from:

• 1964 Impala sold $20,598, Sep 2026 (Hagerty)
• 1964 Impala sold $32,100, Jul 2026 (Hagerty)
• 1963 Impala high bid $34,352, Oct 2026 (Hagerty)

What to check

• Bids usually climb near the end; reserve status is not shown, and Hagerty adds a 7% buyer's fee
• Check the lower rear quarters, trunk floor, rocker panels and the body mounts; the X-frame cars also rust at the rear frame kick-ups
• The listing only mentions paint imperfections; ask for undercarriage photos or a video
• Confirm how the 454 swap was done: motor mounts, cooling, transmission crossmember and a rear axle that can handle the torque
• Not an SS; don't pay SS money if it carries SS trim

Making it drive like new

The big-block and TH400 are already in. Next steps would be a modern coil-over front suspension or at least upgraded springs and sway bars, a stronger 12-bolt or 9-inch rear, rear disc brakes and an overdrive transmission for highway use.
