Okay forget the zoom, zoom. This is a small mini van for families who primarily take short trips around town carrying 2 kids and a lot of stuff or 3-4 kids with bare essentials. If that is what you want, then the Mazda5 will not disappoint you. Fuel economy ought to be better but is respectable, fit, finish etc. is also satisfactory, as is driving experience and comfort (note I'm a large person too). Reliability has been fine except for the brakes which need an expensive servicing that, so far, the dealer claims is not covered by the warranty. Please note, I'm writing from Canada, U.S. customers might have different experience with warranty service.
Mazda steering. Unlike other family centric vans, SUVs, Cross-overs, and a couple large sedans we looked at, this thing goes where you point it whether you are driving fast or slow.
Second row seats. They are very good economy class buckets and they seemed comfortable enough the two or three times I sat in them, but in this class a bench that could squeeze three (as in Kia Rondo) would be a major bonus. Second as noted above, the durability of the brakes is an issue.
