1) you are a smart cookie. In thinking you alone must be happy with your car. Don't let other's Influence how you view your car.
I used to have a very nice 1972 Rally Challenger factory 340-727 8 8 3/4 rear. B5 blue, black vinly top and interior.
Black strobe stripes over the B5 with rally hood was sweet. But I always heard frown face or not a 70-71 car.
Those same guys today would proberly jump threw hoops to own it.
2) I painted my 73 Dart FM3 since paint was free as,was for a 1970 pronect that never happened. And my mom passed away from breast cancer. So did double duty. O one had to approve of the final car other than my wife and I.
Most said wow never thought the car as a whole would look good and recanted.
3) life is short if you hate it things time won't change it swap the front cap or get a car you do like. Before you know it you will have to much In it. And will look butchered as the beak matches the header
I have seen it happen with cars, boats, houses and people. Be happy with what you start with.
Ever meet a person who was with a girl or guy who was a disaster but they were going to fix said person?
NOTE) the 73 bumpers are already sucked in. They pushed them out in 74 and is an easy thing to just drill and rebolt.
