Ha! That's a funny ad - there were no Swift convertbles! Maybe they put the Swift 1.3L into a Metro and forgot to tell us.
I actually already have one of those tucked away in the garage...
Another car for MetroMPG: convertible 1991 Pontiac Firefly (Geo Metro)
At some point, I'll have to decide which one I'm going to keep - the Miata or that Firefly convertible!
