This looks like an old racer.  The roll cage alone is worth some money.  The engine might be worth $325 if it runs like the seller indicates.  The seller also has a set of mounted terra tractor tires for only $150.

“1948 Willys CJ2A Jeep, You can air up the tires, light it on fire & push it down a hill……….but you probably won’t drive this one without a little fine tuning here and there!
It has been converted to a Buick 3.8 V6 engine, but all of the rest of the drive train appears to be original……..Dana 25 in the front…….Dana 30 in the rear.
The tub, firewall and hood have been hacked by someone that shouldn’t be allowed to have any sharp objects. The fenders, grill and frame might be of use to someone, or, you can refer back to my opening line at the top. $325 and it is yours! You could offer me a little less if I appear to be in a good mood.
