By the late '50s GM's lowly Pontiac 'companion marque' was experiencing a huge spike in prestige and popularity. Eventually, he Bonneville, n ostentatious line-topper that epitomized the division's newfound style and performance, ecame one of the hottest names in the automotive landscape. And when you take one look at a classic like this incredible convertible, t's not hard to understand why. The car's retractable roof optimizes glitzy Main Street jaunts.

Not surprisingly, he car's clean fit and finish is almost good enough to turn reflections into reality. And ultimately, t all adds up to one super cool cruiser that, hanks to its spectacular combination of color and trim, as an absolutely magnetic presence!
Speaking of trim, ontiac's first generation Bonneville certainly did its fair share to promote the sale of sunglasses. And, s with its sculpted body, ll of this drop-top's ornate jewelry has, t one point, een restored to excellent condition. At the front of the car, deep chrome bumper seats correct Star Chief parking lamps at the base of a correct die-cast chrome grille. Above that grille, irrored hood trim frames a canted "B O N N E V I L L E" script and intricate T3 headlights. At the sides of those lights, ocket-themed profile spears dissect polished rocker plates, uarded door handles, mall wheel skirts and correct fender-mount mirrors. At the edges of those spears, lassy "Bonneville" scripts and red, hite and blue Tri-power emblems perfectly complement aeronautical fender toppers and Bonneville-exclusive louvers. At the top of the car, olished frames seal factory-tint glass under a pliable white top. That top flows into a massive, ilver Streak-esque decklid, hich hangs a second "B O N N E V I L L E" script between simple trim, ocket-inspired taillights and a small, ower operated antenna. And those taillights reflect a familiar continental kit, hich is propped on a correct faux sport bumper and subtle, olished exhaust tips.
When Bunkie Knudson began Pontiac's revival, irca 1956, e started building a performance powerhouse. By the time the division's 1960 models rolled down the line, t was literally dominating NASCAR, HRA and Pike's Peak. That stellar showing was no doubt thanks to engines like this Bonneville's retrofitted Tempest 425 V8. At the top of the spry mill, ind whips through a black, ingle-snorkel air cleaner in to a trio of familiar Rochester carburetors, hich cap a traditional iron intake. At the sides of that intake, tamped steel valve covers split the difference between factory exhaust manifolds and 7mm Hi-Temp Radio Suppression Cables. At the ends of those cables, n old school points distributor aligns with factory wiper components and a correct master cylinder. A correct radiator utilizes pliable hoses, imple squeeze clamps and a correct shroud to provide ample cooling. A reproduction Delco battery jolts a tagged Delco-Remy generator. And overall, his Poncho's glossy engine compartment is fully sorted and ready to roll!

The car's solid floorpans are coated in thick black paint, hich, omplete with factory drips, erfectly complements a sturdy Aero Frame X-frame. A proven Strato-Flight Hydra-Matic 4-speed spins a correct GM axle that literally sails the engine through its broad power band. Under that capable drivetrain, factory-spec suspension is equipped with factory power steering. Power-assisted drum brakes provide adequate stopping prowess. At the center of the floors, correct exhaust system utilizes correct turbo mufflers to weave an aggressive, ull throttle rumble into a subdued and classy idle. And, t the corners of the suspension, reat looking 8.50-14 BF Goodrich Silvertown whitewalls frame stylish Pontiac wheel covers.
In the '50s, M was the king of design. Period. And this Bonneville's correct Gray and Silver interior is one of the most beautiful cockpits ever mounted behind a motor. Broad and fastidiously crafted, he car's rare hardback bucket seats feature standard leather hides. There's a stylish dash that's based in gray, rimmed in brushed aluminum and equipped with chrome-rimmed gauges, deluxe radio and a correct factory clock.
