Edmunds has published a head-to-head battle of the 2007 IS350 vs. the BMW 335i, and while the results are fairly predictable (Shock! The 3-series wins again), a point must be made that the test itself was skewed in favor of Bavaria.
With performance being the main point of the comparison, the 335i was equipped with an optional $1,700 sports package, while the only options given to the IS350 were luxury appointments like the $3,990 navigation package and safety features like the $2,900 pre-collision system/dynamic radar cruise control. Considering this, is it any shock that the 335i outperformed the IS350 or that the Lexus was more expensive?
How can you draw proper conclusions when the test subjects are uneven?
