No lie: a bolt flew into my car -- which the dealer said was possibly from the side of the road -- which destroyed the carburettor, and consequently the engine needed to be rebuilt. Augh!!! Beyond that, all I do is change the oil every 2,500 miles and it's good to go.
This is a great economy sports car, and very inexpensive (I recently read the car was $11,000 new in 1992, but still worth about $4,000 now -- a fairly good return for an eight-year-old car). Fun to drive and handles curves very well!
I too have a 1992 GEO Metro and it has given me nothing but good service.
When I bought it used it had approx 75000 miles on it and now it has 161,000 miles and still runs well. I did have a lifter go bad, but after having it fixed it runs well.
It is a good economical little car and especially a good work car. Don't know if I will ever wear it out.
