76 C-body as daily driver

Okay i had a mercury tracer as my daily driver and my son wrecked I fixed drove it for another month and the trans in it. well i been looking for a daily driver my freind bought this a few years ago and was going to derby it but the body was to nice so it got parked behind his barn. it has a 440 under the hood with AC not sure about any thing else. 1) what kind of gas milage would it get, wife does not like the idea of another gas guzzler coming home. 2) how do you think it would drive in the snow. and i know every one needs a pic. oh and the price is right
