Ive got a 2010, and if youre going to have it for 10 years i would recommend staying away from the boats with the BIG screens. no telling on how much that will cost when it breaks. X15 is a good solid boat, but with the surf tabs the wake surfing wake sucks. i dont surf anymore anyways. wakeboard wake with about 2500 pounds is just about as good as it gets.
Go with an 08. so you get the updated interior. im not really a fan of the 07 interior.
