Definitely upsides and downsides to both Super Cs, and As. I've had both, and have the A right now. The biggest downside to an A IMHO is the old saying "you arrive at the crash first." Nothing but some glass between you and anything bad that might happen. Also, generally if you want the wife to drive, she's going to feel way more comfortable in a truck-cab Super C than an A. But, you lose way less living space to a cab in an A, and with the driver/passenger seat spun around really you don't lose any.
