The IS 350 is the best handling, most comfortable, fun car I have ever driven/owned. It is plenty sporty enough and extremely well appointed. It is also outstanding value compared to its peers.
The touch screen navigation and audio system are terrific and the best I have seen on the market. The back up camera and distance warning system are very useful safety features. Keyless entry is very convenient.
I'd like an even stronger lumbar support. I also think the location of the gas and trunk lock buttons could be improved. I constantly open the gas cap by mistake.
