You almost gave me a heart attack mentioning the Journey. In my own used car research, I came to learn that even the slimiest dealers felt horrible selling a Journey to people, new or used.
As for your other two options - the Volkswagen is expensive to repair and while I'm not too familiar with the Mitsubishi as far as reliability goes, I do know that generally they're considered 'Entry-Level' for a reason. You're probably going to be crammed in any of your 3 options like a can of sardines so chances are, the whole family isn't going to want to ride in your car. I get you had issues with the 5 in the past, but honestly it's your best 6-seater option. If not that, you're going to be much better served by a used minivan.
How often will the whole crew be in your car? One trip a week? Is that worth getting a car that has significantly poorer reliability and/or costs more to repair?
