Well, you have come to the right place. You are about to be bombarded with positive replys.
The MDX is a very nice street vehicle with superb road handling characteristics ( my wife has a 2002 ).
The 4x4 FJ is the premier stock off road vehicle currently produced. When modified, it get's even better.
Will you do much 4wheeling? Look around, there are quite a few Florida off road enthusiests right here on this board. Go to the regional section forum and look up Florida. There's almost always a group of people planning some sort of outing every weekend. And they are all good people.
25k sounds reasonable, but working for a dealer, you should already know that.
Good luck!
