"I have owned 2 BMW 3 series (purchased new) and encountered many mechanical/electrical issues. I was so happy when Lexus came out with the new IS body style...and I'm even happier I purchased it! This is the best car I have ever owned. I'm pretty sure I will stick with Lexus in the future."
"This is my third dance with the latest generation IS series... my 350 got used up by the 13 year old carjacker... worth noting, he walked away from a triple barrel roll at 100 mph + while the cops were chasing him and wound up, upside down, against a tree and walked away unscathed... give their crash rating five stars. Replaced the '06 with an '09 350 which was a fine car but I couldn't resist the call of that 416 HP V8 so I snatched up an F car.
The IS series offers a great ride... to be sure, the ISF is not for everyone... it rides like a street legal race car, goes like stink when you prompt it but is a mild mannered as an Accord when puttering around town, handles as good as good as anything in its class, and stops like you've thrown out the anchor to the Queen Mary.
I love being reminded that it isn't an M3 by those who worship German marques and love reminding back that I will never be on a first name with my service advisor as I was when I drove an A4... German cars break too often and are expensive to fix.
The IS cars are great... 250 too tame for my liking, the 350 is everything you need in terms of performance, reliability, etc. in a daily driver, but the F car just does it for me.
Fun to drive, kind of quirky to look at, you don't see yourself at every other intersection, and when you are in the mood, you can go out and see how many points you can rack up on your driver's license... and again, you get a great, world class sports sedan with Toyota reliability."
"This car is a 10! I have owened 3 lexus, and several toyota and honda models and this is by far the best!!! I have no complaints, I just hope it lasts me a long time, I sold my last lexus with over 180,000 miles an it was still running great! This car is 6 years old with NO PROBLEMS!!! :)"
"Maybe 15th car I've owned in 35 years of driving, (certainly the most expensive as well).
The IS350 is a stunning car in almost every respect. Build, features, amazing power from a reliable engine. Feed it gas and regular oil changes and that is it.
Sadly drawbacks do eventually show up and begin to annoy you. The car tracks miserably on rough roads and concrete freeways. Very twitchy and requires your constant attention to stay in your lane. 500 Mile drives can be stressful and quite tiring on the arms. (To counter "nay Sayers",I now have three complete sets of tires and rims and have had Lexus plus 2 independents look at the suspension for flaws to no avail.) On back twisty roads, the car shows a side of itself that is sure to put a smile on any drivers face.
Other points... What you buy is what you get... Lexus has limited aftermarket support and keeps service manuals to themselves (actually a hefty online subscription price if interested) to avoid home mechanics from tinkering.
Navigation unit is sub-par and most owners have to "Hack it" to make it usable while driving...disappointing. Lack of a fold down rear seat actually does annoy you more than you would think.
Conclusion: If reliability and breath taking acceleration plus tons of geeky toys is your bag, this is a hard car to beat. Easy to set an unwavering budget around it.
If "driving" is more your passion, all the geek toys in the world will on offset the poor distance capability of this chassis."
