As everyone who lives and works in the Irvine area knows, M3s are seriously a dime a dozen. (Especially white and/or silver ones.) There are also way nicer cars around. Maybe not nicer cars normally parked outside overnight, but still - a random attack seems unlikely. I've seen AMGs and Porsches parked overnight in my garage who obviously thought nothing of it (granted - I'm a little closer to Newport, and covered, but still.)
All my friends and I have modded (and conspicuously-colored) Ms, and the only place we've had any problems has been out of OC. (A concert in San Bernardino ended up with a keying and a stolen side gill.)
As a member of the M family, my condolences go out to you in this difficult time. That said, you have insurance, and it looks like a great opportunity to get a new paint job. All is not lost.
I also live in this area but I work in Downtown LA. However, I am always driving around those buildings and my wife works nearby.
It really freaks me out to see this stuff but I also have a hard time thinking its random, but who knows parking overnight could have drew in some crazy drunks kids (not common in the area).
I also agree, there are tons of M3s heavily modded, GTRs, AMGs, R8s all around this place. I was actually suprised at how many of my neighbors have M3s which made my car feel common...hence the mod bug.
