No service records, no idea, how it was driven, no idea.
My personal truck, 2007 f150 130k miles. I'd drive it anywhere. Uses no oil, leaks none. Drives much like it did new, 75% of the miles have been at 73.5 mph on 300 mile trips.
I've seen some trashed rigs with less than 100k miles. Poor service, driven hard.
So.. it all depends on the van.. Get it check out, then it depends on price.
I personally prefer to buy year old vans with nder 20 k on them.
Last van I bought had 50k, but the price was to good. ($12.5 ) So far no an issue.
