I recently purchased a low km 3rd gen Liberty Rx. I have fixed a few small things wrong with it and now im thinking about selling it and upgrading possibly to a 4th gen Liberty. from what i have read the 2.5L engine seems to be the best engine choice for both generations but how does the 4th gen compare to the 3rd? I have a friend who says the 4th gen isn't meant to be as good as the 3rd gen, however he is biased as he is currently on his third 3rd gen liberty, due to no fault of his cars.
I'm interested in anything anyone can tell me about the performance, handling and reliability differences.
Cheers in advance.
