Word on the street -- and by that we mean Reuters -- is that Tesla's looking to go public with the company "any day." The luxury electric car make, whose Roadster still goes for a cool $109,000, would be the first US auto company to offer an IPO since Ford way back in 1956, says MSNBC. Quite a notable event, indeed, but earlier comments by Tesla investors (via Autoblog Green) suggest "any day now" might be any time between now and September 2010.Filed under: Transportation
