maybe check out the old lincolns, buick is another tank company, Ford galaxy...... check out ebay, lots of classic cars from any era, and lots of pictures because they're trying to sell, but its kind of depressing too.
1966 Dodge Monaco. I actually got to drive one for a couple of months. Gas guzzler to be sure, but it was big, it was smooth, it was powerful, I still have dreams about it.
