After having driven an '05 Acura TL for 16 years and 197k miles, I can't help but think back to my younger days when I drove performance cars like a couple of BMW "M's" and, back in the day, a Z-28. (Yes, w-a-y back.) And that leads me to wonder how long the stock tires will last? Will I merrily drive everywhere like an SCCA road race?
