This is our third Mazda,
Previously:
1. 1994 626, 327000 km,
2. 2004 M3 Sport GX, 214000 km
Picked up this 2010 GX 2L 5 spd in May and just swapped the stock steel wheels (will keep for winter) for alloys. Really happy with the improved fuel consumption over the '04 2.3L (don't have precise figures).
I've been searching this forum for a while and am impressed with the amount of knowledge available (really helpful when choosing the new rims).
