I already have an efficient 2.2 Camry. Now looking to build a luxury full size for fun, but am worried about mpg.

One idea is an 80's Town Car. Swapping to a stick shift out of a Mustang should up it by 2-3mpg easily.

Car starts at 15/20mpg and online forms report that being optimistic. Any advice on a realistic build that could see 19/25mpg? Thanks!

(Also another option that I like less is a Buick 3.8 swap into a 83-88 Seville that should realistically get 18/28mpg)
