The car was parked at a friend's in an upscale neighborhood. For over a year (in the past) I've left my vehicle there with nary a problem. The break-in was between 12:30AM and 6AM. Just days earlier I increased the deductible on my insurance from $500 to $1000 - go figure!
The registration number for the Netbook was entered into a nationwide pawn shop registry, but it hasn't turned up. I didn't have the serial number for the Elna, just an identifying mark I mistakenly made on it when it was very new. So, if you see an Elna SU Air Electronic out there with a purple line coming forward from the throat plate, let me know. :)
