No one knows why the car was towed. The OP says it was because of the expired tags, but that's probably NOT the reason since that should require the police to do so and is almost certainly not applicable on private property. That means that it is probably part of the CC&Rs, or, some contract with the tow company by the apartment management to enforce said regs. It may BE bogus, but, we don't know because we don't have any follow-up info from the OP. To say that you could beat this without knowing any info is more than a tad premature.
