New Wrangler had 6 km on it and after a test drive, was purchased.
Break in was 500 miles at various RPM and load and dino oil change with no significant chaff in the filter. Another 500 miles and switch made to Mobil 1 Extended Performance Synthetic. No oil consumption was observed. Gas mileage was fairly dismal at 20 mpg (Canadian gallon).
You can "feel" when the vehicle is broken in by the performance and engine response. Present mileage is 2400 km. and gas mileage is 24 mpg.
Prior to purchase I was able to test drive four other Wrangler Unlimited Saharas and a Wrangler Unlimited Sport. All of these vehicles exhibited what can best be described as various levels of twitchiness on the road.
The Wrangler I ended up with was the least "twitchy" of the bunch. (Drive her before you marry her)
No problems so far and I'm waving at all the other Jeep drivers on the road. Bottom line - I love it.............
