There aren't any aliens at BMW's "Area 51" test site in Miramas, France, but you won't be disappointed with what is there, should you get the chance to go. Instead of UFOs and crates full of little grey men, the Miramas site holds the testing grounds for cars like the M3 GTS and M3 GT4. And once in a while, BMW brings in a select crowd of customers for a day of fun.

That's what you'll see in this video. Unfortunately, Miramas is an engineer's playground most of the time, so it's off-limits to the public and press. If you want this insider ticket, you'll need to become one of "BMW M's best customers." Or you could just build your own site. We're not sure which would be cheaper.
