can't help with the jeep, but if you need any support/advice/whatever on the accident side of things don't hesitate to pm. i've been through what sounds like a very similar situation. i also was t-boned by someone running a stop sign 4 years ago, and have had 14 surgeries to rebuild my left leg, 1 surgery on my right leg, and 1 surgery on my left hip, not to mention various other minor fractures and internal injuries. numerous bone grafts, skin grafts, ex fix's, rods, plates, you name it!
you've got a long road ahead physically AND mentally, but just remember it could always be much worse and life does go on!
