I'm looking into a used P85+, 10k miles for 82k seems like a good deal at a local dealer a couple of hours from here. The question is, I drive 16k miles or so per year and appreciate comfort and smooth riding, more so that sportier feel. I've never driven a sports tuned car before. Is the ride on the P85+ really that much louder and rougher than a P85? Also, and what may be the bigger issue, how soon will I have to change tires if I'm driving 16k miles per year? This could be an extra expense not worth it for a daily driver. Thanks!
