The only thing I liked better on my BMW Z3 was the body style/shape. This Mazda handles curves like a dream, smooth ride, well thought out interior. Absolutely love the top! Can be put up or down from the driver seat in about 5 seconds. No boot to mess with. Great city gas mileage. Love the combined key/keyless entry remote.
I cannot emphasize enough the ease of putting the top up/down; fine tuning of climate controls (tiny increments; all of the storage compartments (glove box, one behind each seat and one between seats that locks); steering wheel radio controls; multiple cup holders; comfy seats; great trunk space for roadster.
Heated seats as an option would be nice ... find a place to put a spare tire.
