Nothing so far, but only had it a week.
On-road handling & ride are far better than I expected for a true off-roader, though with the short wheelbase it does pitch a little on bumpy roads.
Performance is better than many people have been saying, considering it's weight and large tires and I haven't even come close to redlining it as I'm still running it in. You just have to work out the optimum shift points, and the six speed gearbox has plenty of ratios to play around with.
Interior is fantastic for a true off-roader. Comfy seats and driving position, and the sat-nav system with the hard drive for storing music and videos is great; had to pay extra as an option though.
I wanted to add an addition to this review I left yesterday.
This morning as I was driving to work I ran a red light at 60km/h, while distracted by a car coming up fast on the inside lane next to me, leaving himself nowhere to go as there were parked cars ahead.
At the last minute I realised the lights were red and saw there was a taxi approaching the intersection at speed, so I hit the brakes and swerved to the inside lane, fully expecting to collide with the taxi.
All I can say is my Jeep performed fantastically. The ABS allowed me to steer without brake lock-up and the stability control kept it flat and in control; I pulled up about a foot short of the taxi's front fender.
The jeep performed far better than my previous ABS equipped sedan did in similar situations, so for an off-roader this vehicle has just proven itself to me for on-road safety as well. I was worried after reading some of these comments about the Jeep's on-road safety, but it's proved itself to me now!
ABS, all speed traction control, roll control, ESP, and better suspension technology make the current model much more stable than past Jeeps on the pavement. But cooler yet is that they were able to do this while maintaining its off-road prowess. I sure like my Rubicon. One question... you said that this is a "sport" model. Here in the States the Sport was replaced by the "X" model designation. So is the Sport analogous to our X, Sahara, or the Rubicon? Also is yours a 2 door or 4 door? Cheers!
Yeah, it's a 2-door but not a Rubicon (they're called that here too). The 4-doors are called "Unlimited" and "Unlimited Rubicon"
The entry model 2-doors with the soft-top are called the Sport, but many sold (including mine) are optioned with the "Renegade Pack" that includes the factory hard-top (in addition to the soft-top which is still supplied), side steps, metallic paint and the better sound system with the CD changer and the subwoofer. I optioned mine further with the steel bumper with the chrome bars on each side (looks cool with the black paint) and the sound system with the sat nav and the hard drive together.
I should have added that even the entry level Sport soft-tops come standard with air-con, power windows/doors, cruise control, leather steering wheel, cloth seats, etc, so they'd be nearer to the Sahara in the US market. They don't sell the bare bones ones here as far as I know.
