Soon after I bought it, it developed a minor oil leak, which various mechanics seemed unable to find the source of. The leak grew until the crack in the engine block became noticeable, and then the crack killed the engine at 93,000 miles.
No other problems.
I bought this car because my previous Mazda 323 (a 1989) was still going strong when I sold it at 150,000+ miles.
This one was funny, in that it seemed like it would be just as great, and started out with no problems.
Even after the crack in the engine block killed it, I can't remember it ever having any other mechanical problems.
It had great pick-up, and with the small size, it just zipped around everywhere and was easy to park and maneuver (despite manual steering, which made parallel parking a bit of an upper-body workout sometimes.)
My biggest complaint while I drove it was that the seats were incredibly uncomfortable and the vinyl got awfully hot in the summer.
I should simply pour some crack repair into the Motor then sell it on.
