If you are still looking for a Mazda5, avoid the '06 / '07 models. Only go with '08 and up.

Too many issues on the '06 and '07 models with the big one being the factory alignment issue - they chew through rear tires. In fact, next time you look at a used Mazda5, be sure to look at tread on the inside of tires, make sure there is not uneven wear. While this is a rear tire issue, check all four in case they rotated the tires.
