Quoted from RobT:Bingo.
This really is what it came down to for me in the final analysis. As much as I wanted to wait to see what the JL had to offer, in the end I realized a few things regarding that wait: 1) Even if I like what I saw (looks, specs etc.) buying a first year new platform vehicle from Chrysler is pretty much universally accepted as a bad idea 2) one of the things I would have been interested in regarding the JL is the Diesel, but many people on the forums are saying that the Diesel won't even be offered in the 2018 JL...meaning I would have to wait at least 2 more years 3) The current JK platform is proven, I know exactly what I'm getting 4) The aftermarket parts support for the JK is amazing...to the point of being overwhelming.
I was ready to buy a JK in 2010, then read about it getting the Pentastar so I waited.
My wallet was burning by 2012 when they put it in, but waited again. Thank god I trusted my instincts because even though the Pentastar had been in other Chryslers for years, there were immediate reports of bad cylinder heads and heater cores plugged with goop from either improperly cleaned blocks or the dealership accidentally mixing normal with organic coolant.
I finally bought mine in March of 2013, and really glad I held off.
