If he's finding that the "comfort suspension" to be firm, it really concerns me that every North American model will get the "sport" suspension. I like a sporty suspension just as much as the next guy but on my daily commute I drive 20 miles each way, and I really don't want to feel worn out or beat up after every drive.
What's funny is that if I test drive the CLA and find it too firm to my liking, I'll likely switch to a BMW 328i with a DHP package (adjustable suspension). It's funny because essentially I'd be running to BMW for a more luxurious ride, not a sporty ride. Most people do it for the opposite reason. That's a shame, because I think the CLA is a much better looking car and I really don't want to be grouped into the whole BMW "driver" category. I don't like following the herd.
