Stop thinking and debating. Just get the latest car that serpent has: The 08 720. There's a good reason why they replaced the 710 for the 720. If you decide on the 710, later down the line, you're gonna be saying, " Damn, I should've got the 720. " Trust me, I did this before and wasted alot of funds. Do yourself a favor, get the 08 720
. Goodluck.
