If you need a location do something original that fits the map. Mayberry map is more forestry area with possibly a up and coming Community. I can name a ton of communities like that near or around Houston Texas (like the area where my Volunteer station is). But then again I'm going to be biased.
As for the Taurus comment fact ford sold 2x as many explorers (utilities) then the interceptors. (Roughly 60,000 utilities compared to 30,000) That's why they got the face lift first. If you live in up north or on the east coast of the u.s. you'd say that's what depts are switching too. But I can name a ton of depts that went with the Tahoe and or chargers (Houston, Dallas, Chicago, CHP, Texas DPS) But I don't want to argue.
(Note I only said change up police vehicles because a ton of mods already use Ford's.)
