Why 7.8: A 657 cc turbo triple, a 720 kg curb weight and gullwing doors on a kei-regulation chassis — Suzuki's engine under a Mazda-built body, with unassisted steering doing the rest of the talking. Never federalized, but 25-year import eligibility turned a forgotten oddity into a genuine JDM collector favorite that still gets driven, not just displayed.

The long version
The 25-year window turned it from a Japanese curiosity into the affordable gullwing, and the ownership pattern stayed honest: at 720 kg and 64 hp there is no speculation case strong enough to stop anyone driving it. Owners treat the fragility as part of the charm — parts hunts through Japanese auctions, a practiced climb over the wide sills, kei-car fuel bills. It is bought by people who wanted the strangest possible route to fun per dollar, and that is exactly how it gets used.
