It’s a great SUV, if you like Jeep Wranglers then you should go ahead with the purchase. I would not agree on the statements made of regular breakdowns.
People don’t realize the normal wear of Mechanical parts and expect their Vehicle to run as same as new even after 100,000 km mileage. Yes there are bad experiences that may happen randomly but we cannot class the whole Jeep Wranglers as bad make on few bad experiences.
The Mileage range you are looking for it would not be a problem – as a Jeep Wrangler owner myself, I can assure you that.
Problem you might face is the “Death Wobble” – google it, it’s a common problem with the Jeeps.
I would recommend visiting following “www.carcomplaints.com” , do a bit research before you make the purchase.
Just one comment – its not a family car. Ride is rough and not luxurious. Also, resale is difficult because of limited market in Qatar.
Cheers – hope above is helpful.
