This Buick Riviera convertible is a factory-side prototype vehicle, and it can be yours with just 4,300 km (2,672 miles) on the odometer. The auction will be held in August, and no pricing has been announced so far.
Little is being revealed about the car itself, other than it used to be stored in the GM car collection. It is not, and has never been, street-legal, but is rather well-equipped for a test mule. For instance, power windows and air conditioning are included.
Powering the car is a 3.8-liter supercharged V6 linked to an automatic transmission. In its factory form, the engine produced up to 240 PS (237 hp / 176 kW). The exterior is purple, while the cabin comes trimmed with light-hued leather. The roof is missing on the photos, but the listing states it is a convertible, so we would imagine a soft top lying in that trunk.
