It depends on the SYMBOL of the model, and the age of the car - not so much the engine. The ENGINE is considered in the symbol.
YOUR AGENT can give you a REAL answer.
Your age will definately be a huge factor. I’m alot older than you and when I bought my GT the insurance was about $200 more a year over the regular stang due to the difference in the price of the car. (Well worth it to me though!) That is with a clean driving record, no accidents/no points for over 10 years at the time.
