Amazon offers the Little Tikes Princess Cozy Coupe Ride-On for $38 with free shipping. (Walmart offers it for the same price with pickup.) That's the lowest total price we could find by $8, although we saw it for a buck less in September. It features a removable floor board, parent handle, ignition switch, and removable gas cap.

Update: Amazon has sold out; however, Walmart still offers it for $38. Opt for free Site-to-Store pickup to avoid the $4.97 shipping.
