Yeah, my dad's 2000 SLS gets him 30-32 average (he drives 2 hours everyday highway), whilst my STS gets about 24 (straight highway) and 17-19 in "city";depends on whether or not my wife is driving, then I'll be lucky to get 2mpg
. Says she drives easy but doesn't earn the "Miss Earnhardt driving award" for nothing.
Just got my '91 Eldo running again with the average of 25 city and probably 32-34 highway, I really like the way the Eldorado does it's thing.
