I just received the documentation to sign in preparation for my delivery at the Scottsdale AZ delivery center. I also live in Scottsdale. Everything prior to my purchase indicated that my sales tax in Scottsdale for a vehicle purchase would be 7.15% (I also saw up to 8.05%). However the final sales tax on the paperwork was 8.8%. This difference is over $2000, so I wanted to ask if anyone knew what the additional tax is for, or if I was looking at the wrong info to begin with. Thanks!
