Bought a Mark 3 conversion with 77k miles a year ago for $6,500 - these Dodge Vans seem very cheap. Have used as both people hauler and for antique business for 10k miles with no problems. Expect to replace transmission eventually, heating/cooling controls have a mind of their own, interior & exterior trim are poor. The fuel injected 318 is smooth and solid, always starts. Interior space is fantastic. Gets surprising 17 mpg on freeway at 75. Buy one for $2.5k less than a Ford or GM, then put the money away for any possible repairs and you won't be disappointed. I also found the ride a little less truck-like than my old Ford Van. With the reliable 318 may be the best used van bargain.
Space, engine, good AC, very good stereo, cheap parts, not horrible gas mileage, OK seats. Worth upgrading from an older van for airbags and ABS. Don't expect too much and you'll be happy.
Poor quality fit/finish, electrical problems, don't drive in snow, slightly lower crash scores than other full-size vans.
