I went through the same dilema....went with the gs...you're only young once....save the comfy car for later...If you drive like an old man...then get the ls....but it is way heavier and less sporty....
NO vote for me...it's your car...your choice.

 

in my area I see allot of 04+LS430s, with 01-03 its like on every corner and drivers not only old people most like 30s and up. same with GS each month i see more GS's around, most 98-00.
