Only the hipsters and the luddites seek those out. They're too overprices for something you'll intentionally drive into a tree at some point. Most 4x4 enthusiasts are using pre-OBD2 and 1st gen OBD2 vehicles since they're cheap and plentiful.
We both know a stock 12v is grossly under-powered by early-mid 2000s standards.
And if you've got a close to stock (nobody gets 24mpg with 35s and a lift) 12v powered vehicle that isn't a completely clapped out POS or very, very rusty you're probably not wheeling it much if at all...
Was I close?
