The powertrain warranty goes to 5 years or 60K miles. If you're really that worried about the extra mileage, you can easily get an extended warranty of some sort for less than $2500. Plus, either way, the 3yr/36K mile warranty's up on both of them.
Whichever you buy, get the transmission serviced (by a *trustworthy* mechanic/transmission guy) every 25K miles. Supposedly Honda redid the transmission in 2004 to have less problems than the former one, but those ones are still aging and we'll see what shakes down over the next few years.
Fwiw, we have a 2001 Odyssey, that has 111K miles on it. I *am* going to get 200K out of this sucker - long enough to get these kids grown and then I can downsize to a more normal car.

We had to replace the tranny at 109K miles though (a well documented problem on this model), so that's where we're coming from. If you have documentation and all that, sometimes Honda will [partially] reimburse for the faulty transmission, but once you hit that magical 109K point things get iffier... we're still trying though since we were right on the cusp.

I will say, don't get your transmission done at a dealership, wow. They didn't know a quarter of what our tranny guy knows, and they were more expensive to boot. Hubby's spent some time hanging out
over here as of late.
