Airstream is going upscale.
The 81-year-old maker of the humble silver trailer is collaborating with German automaker Mercedes-Benz on a new luxury motor home.
The Airstream Interstate, which went on sale earlier this month, made its first public appearance Tuesday at the Los Angeles Auto Show.
Airstream and Mercedes began making Interstates, which are based on Mercedes' Sprinter vans, in 2010.
But the newest version has significant upgrades, including a collision warning system, lane-keeping alert and parking sensors. Options include a rooftop solar panel and a storage unit for golf clubs.
Under the hood, there's a turbocharged Mercedes diesel engine that gets 18 mpg on the highway.
The 23-foot-long coach has belted seating for nine adults and sleeps two.
All this luxury doesn't come cheap. The Interstate starts at $146,300.
