Lindsay Lohan left rehab. Again. Bringing her mercedes around this time. Somehow, I think the point of rehab isnt the same as that of a Hotel.

TMZ says:

Lohan, who checked into rehab nine days ago, took her SL500 to Beverly Hills Mercedes for service. She also stopped by the set of her new movie. Lindsay then made one last stop -- at a grocery store -- before heading back to Wonderland rehab facility ... other rehab residents have groused that Lindsay has her peeps come to pamper her -- a masseur, hairstylist, makeup artist, etc. They're also upset that Lindsay has the magic key to the front door.  This week alone, Lohan left rehab for day-trips on Monday and Wednesday as well as yesterday. On Monday, Lindsay left Wonderland for her condo. On Wednesday, TMZ spies spotted her at Newsroom Cafe having lunch with friends. And of course, yesterday's field trip.

So this is like a Rehab Motel. Where you check in after you sneak out to tell them you're brining your car over, and some booze just to make sure you'll feel better.
