IIRC, I'd gone to Falore Nissan (before it became Sunnyvale) and they looked the tires (I believe per the criteria in the TSB) and got the tires replaced. I didn't have the Roadster, so no soft top. Both my power windows failed at almost the same time. Those were replaced under warranty.
FWIW, most things that went wrong on my Z were all under warranty, fortunately. But yeah, my mom's 96 Toyota Camry V6 which she had from 96 until early 08 (when it was totaled) was a lot more reliable than my 04 350Z that I had from late 03 to mid-2011.
My experiences w/the Z, my former Maxima along w/my parents' experience w/their 07 Altima Hybrid are overall decent enough that leasing a Leaf is still high up on my list. Hope to have in a few weeks, assuming I can get a good/decent 2 year lease deal. Looking forward to free juice at work.
Won't need to charge much at all at home, probably almost never on weekdays due to my short commute (~12 miles, one way, w/not much highway).
