I'm thinking of switching to a YZ from my WR and am curious if there are many benefits of the 07 over the 06. Some dealers still have the 06 and I can save about $800 so I'm curious if it's worth it. Any suggestions on best prices in SoCal, Nevada, Utah, etc? I live in Mexico but will be going back to Arizona in 2 weeks and would like to buy it then but I'd prefer to avoid paying sales tax if possible. Thanks!
