Best Cargo Van for 5k?

Looking to get a cargo van to transport a couple dirtbikes around. Here are some that I'm considering, they are all Chevy express 1500. 2008 V6 105k miles for $4000, 2006 V8 102k Miles for $5000, 2004 V6 41k Miles for $6000. Is it worth it to spend more to get less miles? Are the chevys not good, should I go with a ford econoline instead? It just needs to be reliable.

If all you want is to haul dirt bikes, then why not just get a small trailer. You can pull a trailer with a much smaller vehicle and save on fuel and when you're NOT going riding, you can just leave the bikes and all the associated paraphernalia at home.

I'm with JetDoc, but if it's a van you want, get the V8. The V6's will do what you want, but will get the same or possibly worse gas mileage than the V8.
Chevy/Ford vans, both are good, old school, tried & true tough work trucks.
