I know this is probably old news, I tried to do a quick search, but I had no idea PTG doesn't drive BMW anymore, or at least that's what it looks like on their website.
:(

Yep. They switched to Panoz last year. Rahal now manages the Mobile Tradition cars.

that's too bad, anyone know when BMW is gonna get back in to ALMS? I'm sure with the new M3, but other than that?

There is another thread on that started a couple of weeks ago. Autosport is saying next year and potentially with a new team.

Rahal now manages the Mobile Tradition cars.

That now makes sense why Autoweek said the next M3 may be raced by Rahal Letterman in 2009.
