LOL this is such a teenage guy thread. Your criteria is pretty close to what I had in mind when I was 17 and had just moved to Tahoe.
Being serious, It doesn't honestly sound like you have a budget to accommodate everything you want, and getting a truck or SUV would stretch your budget further.
4runners and Land Cruisers are GREAT vehicles (I've owned both) but gas gets expensive quick.
Also, rule out Jeeps. The Jeep crowd LOVE their vehicles and will tell you all day how "bulletproof" they are, but that's not going to help you if you get one and find out just how much goes wrong with them, and that that they need maintenance all the time. Skip Jeeps, especially if you don't have the money, time, or patience for constant repairs.
Honestly, you should probably get a Subaru Forester or Outback and call it a day. Reliable, solid, good MPG, all-wheel-drive, decent ground clearance, and a solid winter vehicle. The speakers/audio components are easily upgraded (though they will never be great unless you get a whole new system) and while they aren't "sick and sporty", let's face it: $10k is not going to get you anything that's REALLY
"sick and sporty", especially with all of the criteria you mentioned.
