A friend is looking for a good deal on a "like new" Tahoe 215xi. He has no idea how/where to begin, especially dealing with a used boat. We own a Mariah Shabat 212z, with a 350, and have plenty of room for guests and have no problem pulling skiiers, etc. I just need some help from folks who own Tahoes on how to advise him. Any suggestions would be welcomed. Thanks!
