Huh?
Modern jeeps are an order of magnitude more complex than prior generations, although using technology which allows reducing complexity.
Jeep offered/offers a huge number of assembly options which results in many more permutations to support. The small number of units sold never justified the many options, which means some replacement parts may never be available due to cost of spinning up manufacturing to produce them.
Jeep would have been much better off if they only offered three variants of any given model (while allowing selecting the paint color), as manufacturers used to do. The products offered should have been the models that customers wanted to buy instead of the models the dealers wanted to sell.
