1976 Cosworth Vega
My Hagerty on my Cosworth Vega was also about $150 a year.
But the trick is that they would only cover the damages if the car was on the way to or from a car show. After that coverage gets really wonky.
I had two policies - one was for static damages (garage stuff) which was the $150. And to and from car shows. But I had a normal policy from Allstate on other issues.
Hagerty also helped out with the real challenges. A fender for a 76 vega is valued at about $25. The reality coverage came from Hagerty.
