There's nothing exotic about the suspension. It features MacPherson struts up front and uses a semi-trailing arm design in the rear. Hard driving on winding roads is okay, but the car could have a stiffer suspension for more serious driving. But it's on the highway where the Riviera shines, with a compliance to the suspension that offers a comfortable ride with good straight-line stability. The suspension does feature automatic leveling.
Passengers ride in leather-covered seats.
And like the exterior of the car, the interior is beautifully designed and crafted. Instrumentation is the standard, with a speedometer, tachometer, fuel and water gauges. The HVAC controls are clearly labeled. Radio controls are mounted on the steering wheel, which means that you don't have to take your eyes from the road when you're changing stations. I had one complaint with the Riviera, and it was a small one.
