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. 

As always with this type of component your best bet is to match the part number to the one on your original unit.
