Well, afaik your Geo Metro
should be a
rebadged Suzuki Cultus/Swift

Unless there's another rebadged version I haven't heard of.
If it's a 3 cylinder Suzuki it'd be economical, but those engines run really rough (not well balanced) and don't last all that long before needing a rebuild.
The 4 cylinder variants are quite good really (for the most part).
