Looking to buy a 2010 - 2011 Jeep Wrangler

I like it because I like the style and because the 4x4 will be useful during the winters. I will most probably not drive in much terrain with it.

Where I live we have some freeways with an average speed of ~80 mph will it be ok to drive with at those speeds? All Wranglers comes with soft and hard tops where I live.

Haven't tested one yet but it's on my to do list. What is the down sides with owning a wrangler?
