When I worked at a Toyota dealership I actually sold an MR2 spyder to a wacky old lady who said it reminded her of an MGB she had back in the 70s.
The main storage area is actually behind the seats. You flip each seat forward and there's a door on the bulkhead which opens up to a shelf. The front trunk, well, ain't much of a trunk at all.
Spec wise the car is more close to 2100 lbs than 2400 lbs, and the VVTi engine has a wider powerband than a Miata, so it's actually a good deal quicker. The Miata catches up in the turns since they're reasonably equivalent in handling but it's easier to steer the Miata with the throttle.
