Thanks again for all the replies. Seems like there are fewer 2005-2007 SR5s than LTDs. Is the only major mechanical difference the airbag option in the rear on the LTD? Was leaning toward an SR5 just for cloth seats vs leather, are there any other differences to consider?
My 05 SR5 has Leather and rear AC. What I like about the SR5 is the lack of airbag (I added Firestone Airbags) and lack of the rear wing (which interferes with long things on the roof) and the lack of the Nav/entertainment system. Besides Limiteds coming with 17 inch rims (my SR5 came with 16's and when I go to bigger calipers I will need to go with bigger rims) I actually cannot think of a good reason to get a Limited and would recommend avoiding them if possible.
