Average front-seat dimension: 46.8 inches Tall drivers with bank accounts as lofty as their heights will love the S-Class even though the $95,000 car from Mercedes-Benz ( DDAIF) is the most expensive model on Edmunds' list. "The Mercedes S-Class is just a wonderful car," Clarke says. "It's got world-class craftsmanship, a wonderful cabin and tons of available convenience and safety features." Although the S-Class driver's seat offers the least amount of headroom (37.8 inches) and legroom (41.9 inches) of any car at or near the top of Edmunds' rundown, generous hiproom (60.8 inches) more than makes up the difference. At the same time, even the least-expensive gasoline-powered S-Class (the S550) comes with a 429-horsepower V-8 engine. A top-of-the-line S65 AMG features a mammoth 621-horsepower V-12, while Mercedes offers hybrid and diesel S-Class models as well.
