Hi Michael,

As far as we know, the ST-Line doesn't get firmer suspension, and having driven it, I can confirm that it is a comfortable car. Saying that, I have not tested it back-to-back with the old one, so I can't say for sure how it compares. One thing to watch out for: the new Titanium model comes with smaller alloy wheels than the ST-Line model does, which means a thicker tyre sidewall and, usually, better comfort. So the suspension itself may not be different, but the ST-Line car is still likely to be a little less comfortable than the Titanium.
