I've am soon looking to buy but can't decide between the RT & RTS. It seems like there is at least $2K difference which seems like a lot. I saw one post saying the RT seats are not as comfortable. I know the fabric is different but how about there 'seat of the pants' comfort? I'd be interested in hearing about your impressions as well as any other observations about quality/functionality of such things as the sound systems, digital dash readout (?), security system, etc. Thanks for sharing your driving experiences between the two.
