A Camaro is considered to be a "sports car'. This will raise your insurance premium.
Considering it age....30 years old...you will have a difficult time finding parts for it, unless you like searching through junk yards. Over 25 years old....you may be able to register it as an antique.
Because of it's age, you probably won't be able to get collision/comprehensive insurance....only liability insurance.
For lower insurance rates try convincing your parents to add your car to their policy....knowing that if you get a ticket, or have an accident, their insurance premium will double or tripple.
Go to an insurance agent that represents more than one company. Ask them to shop around for you, and get you 3 estimates on the cost of insurance....also what kind of car is cheaper to insure.
