That is a 72 CLONE 13k is not too far off the money for a car like that....maybe a little cheap but not ridiculous....just fyi ALTHOUGH it is claimed low miles...the b uild sheet and protecto plate mean nothing since the ad says it is a clone(owner added SS package) these items are usually used to prove a factory SS car.
still might be a scam IDK but it's not a big money car in my opinion.The guys on the Chevelle forum guestimated mine worth 15k maybe as high as 18k if someone really wanted it....it is a 72 malibu that I turned into an SS
( 454,muncie 4 speed 4.10 12 bolt buckets/console, cowl induction,SS dash with tach and gauge package) It also has disc brakes.
