Mazda 3 5D 2.5S

Anyone know if this is a good car or not?

As others have commented, for the rather large price hike for the 2.5, it only has marginally more power than the 2.0.
There were very few of them sold in Taiwan, and weren’t very popular at all.

Are they good? Yes, but I’d typically recommend the 2.0 instead, or add some extra cash and buy a better performance vehicle.
