You can always try their insurer, but actually proving negligence on their part is going to be very hard in court. First, the complex has no duty to you to provide *ANY* level of security for parked cars in almost all cases. If you had a locked common garage, you might be entitled to expect such, but an open lot is pretty much nothing. Second, you'd have to show their lack of lighting or other security is a foreseeable cause of the vandalism. You think a few floodlights is going to stop a tire slasher?
