Buying used 2012 questions

Hello. I am possibly looking at a 2012 with 2089 miles on it. I am in PA and the buggy is in OH. Would be using it for trail riding, hardly any work with it. Like the thought of the bed as an area for the dogs if we take them out.

What key problem areas should I look at?

I read that bushings are not sold individually...is this true or is there aftermarket?

How is the durability on the engines?

Thanks for any help!
