WORTH?? 72 Dart

certainly would not call it a perfumed pig, appears to be a nice cruiser, esp if it REALLY has a 340 and a 727 and a 8.75 rear end. HOWEVER it depends totally on what YOU are looking for? ( I know I will get flack for this but here goes)
The car is worth what it is worth to you.....( purists will certainly argue this point) BUT a well fashioned clone for less money is the way to go. You get all the benefits of a hotass muscle car for about a 1/3 rd of what a purebred costs.....if you are just starting out shop around check ebay and a few other sites on what the model you want goes for, match that to your budget and select one. THEN take it to a local restoration shop and have THEM look it over and check it out and give you an opinion. from there it is all up to you.
that car if it is NOT all doe'd up has a real 340 and 727 and a 8.75 could bring 10k in yesterdays market might go as high as 20
Check the brakes make sure you have the big set and NOT the /6 versions....beyond that its your call....it does look nice....how does it run? any smoke?

for the love of God, PLEASE get that GM corvette style air cleaner off there, that's just blasphemous
