Consider one based on the Ford Transit van. We have a bunch at work and have had few problems most have 200k with a couple 300k. And any Ford dealer should be able to work on them.
Remember in the 80s and 90s ADHD was the in diagnosis for all the little darlings that the parents were too lazy to make behave. Now the in thing is autism.
Don't get me wrong, there are some that legitimately suffer from ADHD and autism and it's a disservice to them to class every ill behaved...
