Id say Q7, but I dont think its as roomy as an LC.
My personal suggestion? : Keep the LC 2005. I love that shape and the gray color looks sweet on it(Y)
Though if you MUST get another, how about a Q7 / X5 / ML / Toyota 4runner -
The 4runner/Hilux Surf SUV looks awesome in black, even in white/silver/blue (Y)(Y). Get the 4 cam 3400cc V6 (Y)
