INDIANAPOLIS — Honda found out the hard way that just because it put a fancy suit and snooty logo on the working-class Civic didn’t make a luxury car. We’re talking about the ILX, which shares architecture and assembly space with the venerable compact Honda. Early ILXs were noisy, rode harsh, and weren’t up to their price. In fact, many felt the Civic Si was a better all-around car for less coin. For 2016, the ILX trades sass for substance.
