I'm trying to decide if the air suspension is worth the cost both upfront and in future repairs should it need attention. I am not considering it for performance purposes. I don't live on a dirt road, nor in an area that has lots of blind hills. I do live in CO where the snow can be a factor and do have a sloped curb onto my driveway that will be an issue if I hit it too fast. I don't think we're passed the warranty period for any current MS's, so I don't know if anyone can comment on repair costs yet. Are there MS owners who have air suspension and use the features regularly for other than performance reasons (e.g., lowering the car at high speeds)? Are there MS owners who do not have it and wished they had gotten it for reasons they didn't consider at first? Thanks much for your thoughts.
