This segment should have gone to turbos by now but it is what it is. The car accelerates quite well. It can even lose traction going into second gear. The ride is actually smoother than my old 2009 IS 350 which surprised me. I'm getting a little over 19mpg which is fine. As a hard drive based nav system, I would have expected less keyboard lag but I have not tried other brands so I don't know if it is worse or better than others. Also, I get annoyed when I drop the car into reverse and have to wait for the backup camera. Sure, it is only a few seconds... but... Anyway, I'm very happy with the purchase.
THE DO EVERYTHING SUPER SEDAN!
2012 Lexus IS FDan Lee - Oxnard, CA09/18/2016
This car is the ultimate do it all vehicle, it has supercar performance 0-60 in 4.2 seconds and 1/4 mile in 12.5@114mph all factory, gets great highway gas mileage, has room for 4 adults yet is reliable and maintenance free as any Lexus. It has the versatility of a 4 door sedan but the sharp handling and braking of a 2 door sports car.
Skip the problematic German M3 and C63 AMGs, go with the ISF for all the performance, and none of the headaches. The 2011+ ISF is both quicker than the M3 and C63 AMG around Car and Driver's Lightning Lap Test and has made it into the top 10 fastest sedans in Lightning Lap History. A truly amazing feat.
Great Car with no Worries about Reliability
2008 Lexus IS FBeastie - Virgina09/25/2011
The ISF is a great car for a speed freak. The seats surround you and coddle you when taking corners. This car does not have a luxourious, comfortable ride. The F is not made to be comfortable touring car. The F does what it looks like it does. It is rocket with great handling. You will get looks and plenty of challenges from other cars/drivers who want to race. I try to ignore most of them, but there have been times when I have complied and the F has not let me down yet.
