I own a Suzuki Swift, with fog lamps. aero package and 5 sp. manual, but don't think it's available in the U.S.
Besides, a "mom car' has got to have at least a V8!
Depending on where you live, a Diesel engine (with turbo) is known to have lower emissions, and with the high torque, would be easy to fit a load of soccer kids in it without being bogged down.
Though, if you drive like my mom (getting us kids to hockey on time), a high efficient V8 sport utility vehicle would probably suffice!
Going as far back as 1979, my mom had a Pontiac Grand Prix, with a small block V8 with spunk--saved us kids from a lot of detentions!! (So did mom's driving!)hehe!
