Have to question your quote.

"BTW My dad's 92 Cadillac sedan got 29 MPG. Not all land barges are guzzlers"

Never been in a land yacht that wasn't a guzzler. No way he got 29 MPG on a regular basis, maybe once, unless it was an Allanté, still questionable. The Allanté was the only Cad under 4000 pounds in that year. GM would have been cruising CAFE for many years if were true. My friend has several 1980-2000 Caddys and Lincolns. Half of that MPG is normal if it is running well.
