This unit offers a 30 day functionality warranty, recently removed from a lightly crash damaged car. The Suzuki swift based cars are fantastic cars, typically even modern-day hybrid model cars can't match the highway mileage of the fantastic suzuki engines these cars came with. Some other models this car may fit, other than the Geo Metro is the Suzuki Swift / Pontiac Lemons / Firefly.
