Bigger was better in the Pontiac lineup before the mid-’60s “muscle car” (mid-sized body with larger engines from the full-size line-up) took over the spotlight, and this ’62’s 425A engine was as hot as you could get in a factory-installed Pontiac mill. The famed dealer-configured Super Duty 421 cars hold ultimate bragging rights on the 1320, but your local naughty Librarian could have ordered this 1962 425A-powered Bonneville convertible and nobody would know until she hit the gas. This claimed six year-old restoration looks OK but not perfect in these so-so pictures, and you can see more angles and a host of supporting documents here on eBay. If you have $70,000 to spare, you’ll get $5 back after clicking Buy It Now, or test your luck with the Make offer button. Thanks to reader T.J. for spotting this wide-track beauty in Coulee City, Washington.

Nothing in this shot would draw a crowd at the local burger stand, unless you pull the air cleaner housing to reveal a trio of Rochester 2-bbl carburetors, the famed Tri-Power setup. You know you’ve won the marketing war when owners of other brands call their 3×2 “Tri-Power,” even though each had a separate name for it. Not shown but claimed in the seller’s description are the 425A’s cast‑iron headers instead of the standard Trophy V8’s “log” manifolds. A shot of the X and O markings on the heads would be nice too, but that will take confirmation. According to AACA, “X” indicates 10.75:1 compression and “O” heavy‑duty valve springs. Pontiac published specifications on the 425A of 348 HP and the 425 lb-ft of torque that gave this 389 cid V8 its name. Working backwards from the car’s performance suggest the actual numbers were notably higher.

Pontiac styling was hard to beat in the ’60s and this drop-top Bonneville looks great from every angle even in this listing’s compromised photos. Eight-lug wheels always please the Pontiac faithful.

Tri-color upholstery and plenty of shiny trim inside and out highlight the Bonneville’s flair, and there’s nothing like a convertible for soaking up the sun and scenery while enjoying the rumble of that 389. Would you drop $70k on this hot full-size or save your pennies for a later GTO?





Lots of GTOs or “GTOs” not too many of these left.
