Sorry not that rare of a car. I have 2 in my barn One sounds just like your car and the other may be a bit rarer as it's a conv. also but with the 273 Hi-po and a 4 speed.
once you get into the early A scene you realize they are everywhere. What is rare is seeing one restored to show room condition. They are worth less than $20k in show room condition and it will cost you way more than that to make it look like the wife’s unfortunately.
