殺雨, I have several questions about Wrangler and Project JK

I went to the Project JK' website, it provides a lot of
fancy upgrade. Just curious how much work did you do on your Jeep.

Also, I think my budget is almost approved and I am looking for a used Wrangler as a weekend fun car. According to your experience, what is the major difference between X, Sport and Rubicon?

Since I want to share the fun with my friends, I am also considering the Unlimited 4 door version. But it is much more expensive. I just wonder if its performance matchable with 2 door version.
