Problem is, with the way Body and Armor have been redone, and a lot of other stats dropped, even the vehicles that have been brought in to 4th aren't consistent. Sometimes they're faster, sometimes they aren't. Sometimes they're armored, sometimes they aren't. Sometimes they have electronics, sometimes they don't. And prices have fluctuated wildly, with how money has been rebalanced. I think you'd have guess at any adjustments yourself, case by case.
