Welcome to the club. Based on your last question, it appears you are about as green as me when it comes to figuring out the road-worthiness of a vehicle. Since you are probably not mechanically inclined, yes, it would be a good idea to have a mechanic check out the vehicle prior to purchase. Even though I know next to nothing about fixing vehicles, when I first started out, I at least knew simple things such as checking obvious items such as oil leaks, engine overheating, odd noises while driving. Taking the vehicle for a test drive in city streets and on freeways will tell you a LOT about the vehicle. If you are truly interested in the vehicle, insist on doing a test drive. For example, the van I purchased through a used dealer drove fine through city streets. But when I drove it on freeways at over 60MPH, the entire rig rattled with intense vibration. It turned out that the rear shock absorbers were completely shot, so the dealer replaced it at no charged which saved me several hundred dollars. By simply driving the sucker at freeway speeds, I was able to tell immediately that something was abnormal. As for which type of van to get, that depends if you will be parking it on city streets or somewhere in the suburbs with more space. If parking on city streets, you want something that is stealthy and nimble for parking and driving. Do NOT get an RV for parking on city streets. Don't even get a Class B van because it looks too much like an RV. Get something rather plain and ordinary that blends in. If you get a used van in the mid 1990s, those usually go for somewhere between $2,000 to $4,000. Personally, I'd get something 1996 or later due to diagnostic engine check tools changing in 1996. For example, even the freakin' Ford dealer can't even diagnose some of my check engine warning lights on my 1995 Ford van because they don't have the older style diagnostic tool any longer in stock. Seems absurd, but true. So given a choice between 1995 or earlier, or 1996 or later, get the latter.
