Hello all, I am wondering your thoughts on a 2010 toro "commercial" unit with a 48 in deck. 0 hours at dealership, a deal from toro hq. asking $8999. Also the dealer is willing to give me a great price on my trade in, a 2000 z147 with 501 hrs and a 44" deck. What do you think my trade in is worth, and is this unit a good buy? I appreciate your comments.
