Getting a 2005 x3

[ON9]

Hi guys,

I am new to the forum and I'm about to get a 2005 x3 here in Boston. Found a dealer who's selling me the 3.0 with sport/premium/cold weather package (wanna get navi but there are no cars in the region with both sport pack and navi) for $1200 above invoice. This price, together with a low money factor, makes the lease option pretty attractive. But since the 2006s are just around the corner, you think I should be getting an even lower price on the 05? Is this a good time to get the car or am I better off waiting for the 06s?

One more thing. Will I need winter tires or am I good to go with the stock all-seasons?

Thx.
