Should I buy it? 1963 Chrysler Imperial

I recently had my Valiant totalled, and am in the process of looking for a new daily driver. There's a 63 Imperial a few miles away from me for $2500. The guy told me he recently rebuilt the 413 in this beast. I know Imperials are very sought after cars in the Mopar world. My only problem is, it would be my daily driver. I thought my single barrel slant six drank gas, but I don't think I know what I'm getting into with this monster of a car, with an equally monstrous sized engine. I'm wondering if anybody on this site has had any experience with these cars, and if so, could give me some tips and "what to look for" issues or details before I buy. I know it isn't an A body, but being a member of this site, I figured it may be a very good place to find information. Which brings me to another question, what type of body is the Imperial? I could also join another of the sister pages to this site and find what I need there. Thanks in advance for any help!
