1971 Buick Riviera in Sandpiper Beige Paint & 455 Engine Sound

Tim Hall says he bought his 1971 Buick Riviera because he “liked the backend on it” — a reference to the polarizing “boattail” design GM design chief Bill Mitchell pushed through against dealer skepticism. Lou Costabile catches up with Tim and the Sandpiper Beige coupe at a small-town Illinois car show, where decades-old opinions about the shape are still being argued out in the comments. The 455 under the hood is almost an afterthought.

Tim Hall didn’t buy his 1971 Buick Riviera for the engine, the options, or even the color. He bought it, in his own words, because he “liked the backend on it.” That’s not a throwaway line — the 1971 Riviera’s tapered rear end, nicknamed the “boattail,” was one of the most divisive design decisions General Motors made in the entire muscle car era, and Tim has been living with that decision, happily, since 2008. Lou Costabile found him and the car at a small-town Illinois car show, and the story that follows explains why a shape some people hated in period is exactly what collectors chase today.

The Backend That Divided Buick Dealers

When GM design chief Bill Mitchell pushed the boattail concept through for the third-generation Riviera, not everyone inside the company was thrilled. Sales figures backed up the skepticism — the 1971 Riviera sold in noticeably lower numbers than the more conventional 1963-1970 cars, and some Buick dealers reportedly weren’t fans of the design either. But the shape survived through 1973 before Buick softened it into something more mainstream, and that three-year window is exactly what collectors now single out.

Bill Mitchell’s Boattail Gamble

Mitchell had already reshaped American car design once with the Corvette Sting Ray, and the boattail Riviera was his attempt to do it again on a personal luxury coupe. One commenter compares him directly to his own mentor, Harley Earl, crediting Mitchell with a rare gift for creativity that GM — and its fans — are still grateful for decades later. It’s a design that asked buyers in 1971 to see a boat-tapered rear deck as elegant rather than strange, and enough of them eventually did.

455 Cubic Inches Under Sandpiper Beige

Tim’s car pairs the boattail shape with a 455 cubic inch V8 — Buick’s largest engine of the era, built for effortless highway torque rather than drag strip bragging rights. Wrapped in Sandpiper Beige paint with a dark brown vinyl top, the color combination softens the aggressive rear styling into something closer to understated luxury. One commenter, recalling a nearly identical 1972 example his family owned, remembers it as reliable and comfortable across a quarter-million miles — a very different kind of muscle car endurance story.

A Car Tim Chased for Years Before Owning

Tim has had this specific Riviera since 2008, but the appeal for him traces back much further than that. He’s not alone — several commenters describe childhood memories of being driven around in a parent’s or grandparent’s boattail Riviera, with one recalling being asked as a four-year-old if the car was a spaceship. That kind of formative memory is exactly why cars like this generate waiting lists decades after they leave production, long after the original buyers have moved on.

Why the ’71 Beat the ’70 and ’69 in the Eyes of Collectors

One commenter, who says he remembers all three model years firsthand, lays out a clear hierarchy: the 1969 Riviera was beautiful, the 1970 was a letdown, and then the 1971 boattail arrived and reset expectations entirely. He places it alongside the Oldsmobile Toronado and Ford Thunderbird as one of the most distinctive American cars of the period — high praise from someone who lived through all three generations as new cars rather than as collectibles.

The Fuel Crisis That Killed the Boattail’s Momentum

The boattail Riviera never got the chance to fully prove itself commercially. By the time Buick toned the design down for 1974, the 1973 oil crisis was already reshaping what American buyers wanted from a personal luxury coupe, and the more conservative Rivieras that followed didn’t sell any better despite losing the polarizing shape. In hindsight, the boattail wasn’t killed by unpopularity — it was caught in a market that changed underneath it.

From Polarizing to Prized: The Riviera’s Second Life

Decades later, the same styling choices that cost Buick sales in period are exactly what collectors now seek out. Several commenters describe actively hunting for a boattail Riviera of their own, treating the design not as a liability but as the entire point. It’s a reversal that plays out again and again in the collector car world — the cars that were too bold for their own showroom often end up being the ones nobody can stop talking about fifty years later.

What a 1971 Riviera Says About GM’s Design Risk-Taking

Tim’s Sandpiper Beige example is a reminder that not every GM design gamble of the early 1970s came from Pontiac or Chevrolet muscle. Buick, a division built on comfort and restraint, briefly let Bill Mitchell put a genuinely radical shape into production — and customers like Tim have spent years since making sure that gamble gets remembered as a win.

How the Boattail Compares to Its GM Cousins

The 1971 Riviera wasn’t General Motors’ only personal luxury coupe chasing a dramatic silhouette that year. Oldsmobile’s Toronado and Cadillac’s Eldorado shared the same E-body platform — and went front-wheel-drive with it — but Buick stuck stubbornly with rear-wheel drive under that boattail sheet metal, then still took the most aggressive stylistic swing of the three. Where the Toronado stayed relatively conservative and the Eldorado leaned into sheer size, the Riviera’s tapered rear deck made it the platform’s most talked-about variant — for better or worse, depending on who you asked in a 1971 showroom.

Restoring a Boattail Today

Because the boattail Riviera only ran for three model years, certain trim pieces and the distinctively curved rear glass have become harder to source than parts for more common GM coupes of the era. Owners who take on a full restoration often report the body panels and interior components as the most time-consuming pieces to track down, while the 455 itself — shared with other large Buicks of the period — remains comparatively easy to service and rebuild.

Why the Boattail Still Photographs Best From Behind

Car photographers have long noted that the boattail Riviera is one of the rare designs that rewards a rear three-quarter shot more than a straight-on front view, precisely because the tapering deck lid and wraparound glass only fully read from that angle. It is, fittingly, the exact vantage point Tim referenced when he explained why he wanted the car in the first place — proof that the detail he fell for is the same one photographers still chase.
