I,m in the same situation - $3,125 with interest accrued for vehicle registered for 0ne year in 2003. The car has been registered in the state I moved to since 2004. I wasn't aware I owed taxes on the vehicle and wasn't notified until the interest grew larger than the original bill. I own no property in CT, and have no plans of ever returning to the state. So,what happens if I do not pay? Does anyone know?
