The 1970 Buick GS Convertible has long been regarded as the “gentleman’s muscle car,” offering a sophisticated alternative to the more rowdy offerings of the era. This specific example, identified as Lot R650 for the Indy 2026 auction, has evolved far beyond its factory roots through a comprehensive professional restoration. By marrying the timeless A-body silhouette with a modern 6.2L LS3 powerplant, this Buick represents a top-tier restomod that prioritizes both high-speed performance and modern-day reliability.
Refined Silver Paint and Muscular Proportions
The exterior of this Buick GS is finished in a sleek Silver that highlights the car’s aggressive yet understated body lines. As a convertible, it features a premium black cloth top that provides a sharp contrast to the metallic finish when raised. The car maintains its iconic muscle car stance, further enhanced by the addition of redline tires that nod to its heritage while hinting at the modern mechanicals beneath. Every inch of the body reflect the quality of a professional build, ensuring it stands out on any concours lawn or cruise-in.
Modern Instrumentation Meets Classic Cabin Luxury
Inside the cabin, the atmosphere is a perfect blend of 1970s style and 21st-century technology. Black bucket seats provide supportive comfort, flanking a center console equipped with the legendary horseshoe shifter for the automatic transmission. While the aesthetic remains largely period-correct, the driver is treated to a Dakota Digital dash, providing precise, real-time data for the modern powertrain. These upgrades, combined with the classic interior layout, create a functional environment that is ready for long-distance touring or spirited weekend drives.
LS3 V-8 Power and Pro-Touring Handling
Beneath the hood, the original engine has been replaced with a formidable 6.2L LS3 V-8, a choice that significantly elevates the vehicle’s performance profile. This modern small-block sends its power through an automatic transmission, providing a seamless and potent driving experience. While exact dynamometer results are not provided, factory benchmarks for the LS3 typically sit at 430 hp/436 PS and 424 lb-ft/575 Nm. To manage this power, the car is fitted with a Hotchkis suspension system and Wilwood four-wheel disc brakes for superior stopping power and handling.
