With the 2000 Volvo S70 STD Sedan's 2.4-liter, 168-hp engine, you can look for 20 mpg city and 28 highway from the manual transmission; knock one mile off each with the optional automatic. Luxuries such as power seats, leather, and sunroof are options, but even without them you're scoring big with all of the included safety features and the car's general durability.
