Lexus GX Real Gas Mileage: Pros
YearBody/PowertrainComment
2008 4dr SUV 263-horsepower 4.7L V8
5-speed automatic AWD w/low range		 The GX has a 4.7l V8, but gets similar mileage to our old V6 powered Ridgeline, about 18 mpg. Very good for a V8. see full Lexus GX review

Mercedes-Benz SL Real Gas Mileage: Pros
YearBody/PowertrainComment
2006 2dr Hardtop conv. supercharged 493hp 5.4L V8
5-speed shiftable automatic RWD		 Awful! Big V-8 gets approximately 14 mpg, if I'm lucky! see full Mercedes-Benz SL review
Mercedes-Benz SL Real Gas Mileage: Cons
YearBody/PowertrainComment
2002 2dr Hardtop conv. 302-horsepower 5.0L V8
5-speed automatic RWD		 Not great. I averaged about 16mpg in around town driving, about 22 on the freeways. Best mileage observed was in Wyoming, 24.5, coming downhill eastbound from the Grand Tetons. that said, people shouldn't buy this car expecting a Miata, in any way other than Two Doors and a Convertible Top. see full Mercedes-Benz SL review
