1969 Plymouth GTX hardtop with a rebuilt 440 on a driver-grade budget
Real RS23 GTX with a rebuilt 440 and clean title, bid far below what driver GTXs bring.
1969 Plymouth GTX
Sold Why we picked it
The VIN (RS23L9G128640) decodes as a genuine GTX hardtop with a factory 440 four-barrel, and it comes with a clean Delaware title. The seller says the 440 was bored .040 over and rebuilt before 2014, now wears a three-carburetor Six Pack setup, and that the TorqueFlite was rebuilt in 2021. The listing calls it a mechanically sound driver with some patina, paint flaws and interior wear.
Comparable driver-grade GTX hardtops have changed hands for $47,000 to $58,000 this year, so even a strong finish could leave room for a buyer. Bids usually climb in the final days on Hagerty, and the reserve status is not stated, so set a ceiling and stick to it.
Note: Hagerty's search results showed the bid at about $15,000 on October 8, while the listing page itself still showed $6,250, so check the live bid before you plan around it.
The value check
When we found it, the bid was $33,250. Comparable cars in the same condition have sold for $47,000–$58,000, so the middle of the market is about $52,500. That put this car 37% under.
Recent driver-grade 1968-69 GTX 440 hardtops have sold between $47,300 and $58,000 at Mecum, Barrett-Jackson, GAA and BaT. The current bid of about $15,000 is roughly 70% below the midpoint, though bids on Hagerty usually climb before the end.

What to check
- Six Pack induction is a later conversion; the car left the factory as an L-code 440 four-barrel, so judge it as a driver, not a numbers-correct restoration
- Rust check: rear window channel, trunk floor and drop-offs, lower quarters behind the wheels, and front floor pans under the carpet
- Odometer shows 11,800 TMU; the seller says the speedometer was reset before their ownership
- Confirm the engine block stamping matches the VIN partial shown in the gallery
- Look for a fender tag and broadcast sheet; neither is mentioned in the listing
Making it drive like new
A good base for a pro-touring B-body: keep the 440 but add a modern overdrive (A518 or a TKX swap), front disc brakes, tubular upper arms with larger torsion bars, and a rear sway bar. A Hydroboost or modern booster and an EFI conversion would make the big block easy to live with day to day.
4 builders make a complete chassis for the 1966–70 Mopar B-body (Charger, Road Runner, GTX, Coronet). Compare them side by side, along with what it takes to stiffen the factory frame.
