M body as daily driver?

I am considering buying an M body (more specific a late model Chrysler 5th Avenue/Dodge Diplomat/ Plymouth Gran Fury to start) for daily driving, about 12K miles per year. It would be a part time commuter and part time show car, for now. It might replace my 2006 Dodge Charger in this role. I always liked the M bodies and my favorites are the 78-79 Lebaron and Diplomat coupes. I want to start with something a little easier to drive daily and to find parts for. I also want something I can put miles on and not worry about ruining a classic older car. I can buy an older M body if I wanted a dedicated classic to show later on. I will loose some gas mileage, but I think the up keep might be cheaper. (Some of the required maintenance on the newer Chargers has to be done at the dealer, etc.) I want to get my feet wet with an older Mopar. What are your thoughts? Any suggestions? How is it living with an M body these days? Any input would be greatly appreciated. I am really looking for an M body I can live with and drive for now. Thanks! :icon_biggrin:
