The Jeep Grand Cherokee SRT-8 will fall apart if you try to take it off road. Don't even go there unless your p***s is really really tiny. A regular Grand Cherokee is ok as a starting point. I was considering a Wrangler Sahara until I found my VX. BMW X6 (as above) would be fun if you have money burning holes in all your pockets. I would think for all around on and off road capability you will need to find a used Lamborghini LM002

Or another VX.
