I have owned the is350 for 14 days approx... Ok it's a fun car to drive, the paddle shifters are a bit slow, faster on the 335i beemer twin turbo. I test drove these vehicles, CTS, ISF, IS350, BMW335i, Audi S4, C 63 AMG. Like them all. Ended up with IS350 and it's a good practical choice. Fuel economy is above average, comfort is good. Fit n finish this car is an excellent value, picked up the 09' for 7k less than asking price, car is fully loaded, plus 3m invisible shield, tint, nav. No question about it, great value, fit n finish is...? Well let's just say it's a Lexus.
I switched from an 03 BMW 530i. Yes I gave up a lot of interior room; but thats it! I gained so much more when I purchased this vehicle. It's faster, more reliable, better looking, fit and finish is worlds apart from BMW. Did I mention more reliable; so long to numerous trips to the repair shop. I am really enjoying this ride!
I decided on the IS350 mainly because of the great experiences I had from my IS250 in Asia. It is not a BMW, but I know it's likely to give me less trouble. I upgraded the sway bar with the F-sports parts, and it is definitely worth every penny.
Test drove MB C350, Caddy CTS, Infiniti G37, M35X, Jag XF. All great cars however for me the IS 350 had the most bang for the buck. It is very fast, (5.1 secs 0-60), handling and quality are awesome and Smokey Granite Mica paint with light gray interior is absolutely gorgeous IMO. The ride is a little harsher as the suspension was returned for 2009, however the handling makes up for it and is never too harsh. AND I’ve been averaging 25 MPG about 50/50% city/hwy driving. My Infiniti G35C only Avg 21 MPG... I made the right decision, a lot of car for the money!
I purchased a Lexus IS350 with fabric seats in 2008 autumn. I traded a 1992 Mercedes-Benz 260E for it. My IS350 has average fuel consumption of 23.5mpg, far better than that of 20.4mpg for the Mercedes 260E. The acceleration is very exhilarating, reaching 0-62mph times of 5.2sec, SS1/4miles is about 14.2sec (That's not far from the best data of 13.5sec, of an American media.). Namely, my IS350's level of performance is about the same level as that of the Mercedes E550,the BMW335i,and even a Maserati Quattroporte of 401 horsepower! Max speed of my Japanese version is electronically limited at 180km/h (112mph), but if the limiter removed, it has the potential of reaching 270-280km/h (170-175mph).
