Amazing. My 325is developed very similar problems this week. Full tank; parked; noticed gas mixed with rainwater underneath. (creates a beautiful rainbow-effect in the water) My mechanic buddy, who I trust more than myself, said the seals (or something... I'm really bad with details) can rot and leak... not uncommon. Funny coincidence, although I haven't checked for dents in the tank.

The only other time this happened was when a gas station attendant tried to force gas into the tank after the pump shut off, causing a huge spill. He was doing that pump-click-pump thing, if you know what I mean. Gas was gushing out from underneath the car (not from the nozzle), but he just kept on pumpin, trying to make that extra $10 (I guess). I was inside the station, came out, saw the lake of gasoline around my car, and stopped him. He had no clue. When I pointed to the spilled gas at his feet, he said, "That's bad. You should get that fixed."

Grrrrrrrrrrr... it was more than a year ago... can you tell I'm still pissed? Lesson learned: never, ever get gas in New Jersey (full service only). Anyway...

Edit: re-reading my own advice, I don't know anything about gas tanks, so I'll just delete it and defer to those who do and hopefully when you have it on the lift it turns out to be nothing.
