I've been on all over the place looking at potential future replacement for the ZR2. From sedans to EVs to SUVs etc.The IS is on my short list of cars for consideration of purchase. That and the BMW 330i. Both are the same size and cost. Even though I don't drive much anymore, I appreciate Lexus reliability. I watched the IS350 review by Car Care Nut and he said it's the last of the "old school reliable Lexuses". The turbo 4 in the BMW is a good engine, and gets better MPG. It has more low-end torque also. A good combination. It's not like the IS is slow, though. It would be more than enough power for me.
There is something special about the IS 350 despite being dated. If you're really after the latest and greatest in tech and performance, then a BMW is going to be better.
I find car reviews funny though, and often ridiculous. "This car is slow with 0-60 time of only 6.3 seconds" or "we only got a 0-60 time of 5.3 when they said it should be 5.2" or "we hate turbo 4's and complex modern tech, but we also hate dated proven and reliable powertrains like the IS 350. We just like to complain." or "We hate touch screen everything, but we also hate this dated interior with buttons."
