Re: So these things are pretty decent cars?
If money isn't too much of a problem, I'd go with the Town Car. You get more goodies for the extra cost, standard air suspension (hard to find option on a used MGM). As a good, straight forward everyday runner, you'd be content with the MGM, and it should be less on insurance. If you wanted to go downright cheap for a good, solid runner, check out any local police auctions for a ford crown vic. Vinyl rear seats can come in handy on those bar nights! So, yeah, all in all, it comes down to personal preference.
