I'm figuring two more years at least until the first bar loss. Maybe the correct predictive factors are time plus mileage, with heat also a factor. We are considering buying the car off lease, now that we have an SV Plus for longer trips. My housemate prefers driving the SL, as do I. Since it's guaranteed to have at least 90 miles or so of range for 8 years from new, it's unlikely that we'd find it lacking in range in that period. I'd also be using a Gold Preferred Plus warranty to extend the Bumper to Bumper warranty to six years from new. That's pricey ($2200) if bought locally, but it's a reasonable $829 from one of the dealers who sell it nationally.
