One Lap of the Web: Model S carbon footprints, 911 road trips and the Rover 3500

We spend a lot of time on the Internet -- pretty much whenever we're not driving, writing about or working on cars. Since there's more out there than we'd ever be able to cover, here's our daily digest of car stuff on the Web you may not otherwise have heard about.

-- It's Tesla Model S owner vs. stock analyst in this mathematical battle royale over the true carbon footprint of a Model S. Whether or not you're concerned about global warming, electric vehicles in general or even the stock market, Green Car Reports offers a comprehensive look at the true emissions of an automobile -- green or otherwise.

-- Hagerty brings the story of a trip from California to Amelia Island -- and back -- in a recently purchased 1977 Porsche 911. Despite some hiccups on the return trip, here's proof that a 35-year-old air-cooled 911 can be a (mostly) reliable road trip machine; just bring a spare set of points.

-- The always quiet, introspective Bob Lutz has a new book out that offers some soft criticism of former GM head Rick Wagoner: He was too nice. We suspect there might have been a few other problems too, but check out some choice Lutz comments at the Detroit News, and look for a full book review in an upcoming issue of Autoweek.

-- Try not getting R.E.M.'s "It's The End Of The World As We Know It" stuck in your head as you check out this lovely 1967 Aston Martin DB6 Vantage Volante formerly owned by conductor Leonard Bernstein. Bonhams sold it at the Greenwich Concours for $825,000, a healthy figure to be sure, but dare we say it sounds fairly reasonable?

-- Finally, from that glorious time-suck known as Bring a Trailer, we bring you this 1980 Rover 3500, quite possibly the nicest U.S. SD1 left at any price. There's no denying the sheer beige '80s-ness of this thing, and we think it would look fantastic parked in any garage -- though preferably slotted between a TR7 coupe and an Austin Princess.
