Don't know much about this but what I do know is if it's not on something recent then odds are it might not follow any new regulation set out since new safety regulations might suggest your only allowed to lower/raise the top under slow driving speeds. Depends on construction of the top as well. Many variables.You can use soft tops on certain vehicles up to 35mph. Hard tops are typically 30km/h from what I've seen.
Reliability is one thing i`ll be concerned about since they already produce a naturally aspirated 2.0 putting out 160hp and reports are saying this boosted 4 cylinder will produce as much as 300hp.The only thing is OEM's like to aim for safe levels of power output so we can't expect too much from it maybe just slightly above the competition, enough to give them an edge in power but that's about it.
Plus these days boosted systems in vehicles like this are more for serving fuel econ requirements, better power is just a perk.
Deposit still helps since the wait can vary depending on which batch you get from and when that batch releases. I don't know about you but I rather minimize my wait as much as possible. First allocation owners usually have it the best, after all, car makers want a smooth launch.Really depends on your dealership and how much Wrangler allotment they'll be getting. won't really need a deposit if they're going to be getting a lot in stock. Also heard the Jeep Wrangler diesel is already being tested before its 2019 launch.
