Good news! I always opted for an engine upgrade on any vehicle I’ve purchased. Never regretted getting the Hemi in my WK2 and will definitely order it for my WL 74 when available.I been seeing a few of the WL75's popping up around town. If I happen to see the owner I always politely ask them their perspective on the vehicle. So far everything has been very positive and everyone has basically no regrets. The only "but I wish" that comes up from time to time is the desire for a more powerful V6 or they wish they got the Hemi.
To sum it up they feel the V6 has just enough, but they would of liked to see a little more. Funny thing about the conversation is the closer. "I think its because I'm still learning about the Jeep" is usually what I'm told. Sounds like its a great vehicle and people feel they made the right decision and are adjusting to the new platform.
