Sure, this 1973 Buick Riviera has its original numbers-matching motor, but that's not what first caught your eye. Instead, it's that this big V8 was rebuilt with dual-quads and a supercharger on top. And while this one makes monster power, you'll enjoy so many comforts in this fully built custom coupe.

This coupe has been with one owner all its life, but you can instantly tell it has not been kept anywhere near stock. Instead, you're looking at decades-long labor of love that has heightened the best of everything the Buick Riviera stands for. The exterior really takes the style to a new level. The green paint has a deeper tone than what you got from the factory, and the metallic element offers a terrific modern depth and shine. It's a combination that makes this coupe sophisticated and sporty – exactly what you want in a Riviera. This was one of GM's most dating styles with a well-creased hood line, an artful dip in the door line, and the iconic boat tail rear end that featured wraparound glass and a sharply pointed center. And while the monster motor peeking out from the top of the hood will always be the first thing everyone sees, we bet you've also noticed the custom split bumper front end – something we all wish the factory had the guts to do in '73. These dual chrome kings are a special fit that hug the body form and add extra distinction. These join other great brightwork, like the form-fitting rear bumper and polished 18-inch custom alloys to create an awesome total package.

The camel cloth interior looks great against the green. There's less than 1,000 miles on this build since completion, and so it truly feels just as plush as it looks in the pictures. Plus, there are nice details like the wood-like trim and Riviera logo stitched on the headrests in green. This is Buick's personal luxury machine, so you have room for six people total, or just fold down the armrest in each row for individual comfort. But no matter how many people are along for the ride, the driver is always king. Your seat power adjusts to the ideal position. The wraparound dash gives you easy command of everything from the radio, to the cruise control, to the full gauges (including auxiliary readout trio). The power windows let you show off the pillarless hardtop profile without leaving the driver's seat. And you can comfortably do this all through the summer thanks to the factory air conditioning blowing nice and cold.

The engine bay is a big reason why this car is already an award-winner. Gloss black inner walls funnel your attention to plenty of triple-nickel chrome plating for a show-worthy shine. And while this is tidy and bright, what you really want to know about is the power it brings to the streets. The original 455 cubic-inch block was rebuilt to be a hardy unit. This includes the block decked, bored .60 over, and special oil passages included. It has been fortified with a custom crank, piston rods, and cylinder heads with Crane rocker arms. It was now ready for big power to be put on top with dual Holley 700 four-barrel carburetors and a Magnum 6-71 supercharger. This is a massive power package that the consignor states is rated at nearly 1,000 horsepower! And the header-fed dual exhaust announces its power superiority to the world with a thunderous roar. The original TH400 three-speed automatic transmission was already a hardy unit, but it was rebuilt and fortified to handle the extra power. Plus, the ultra-clean undercarriage photos show fresher bushing, rear air shocks, power steering, front disc brakes, and grippy modern tires. So this big power Riviera is actually a breeze to drive.

The sale comes with a ton of documentation, including the original warranty card, title documentation, owner's manual, maintenance records, service manuals, build receipts, and restoration photos. This is the powerful custom classic that never loses the easy cruiser feeling that's at the heart of every Riviera. It's truly a one-of-a-kind, and now's your opportunity to take it home.
