Ready to pull trigger on a CPO P85. Any advice on: 1. I will put about 15,000 miles per year on the car mainly driving up and down the 405 freeway in Los Angeles. Will the 21 inch wheels be a major pain? Reading the posts looks like I'll need to take in to rotate every 6000 miles and also be more concerned about blowouts. Most P85s seem to come with 21s. 2. Buying CPO mainly so I do not need to finance but curious what CPO finance rates people are getting? The more it approaches a "risk free" rate like 1% the more I am interested! 3. I will be going in to local Tesla store - if CPO inventory in "LA" does anyone know if that means I can test drive the specific car? Thanks - been thinking about Tesla for years!!
