I am superior as “main car” to go back to Cadillac. Should then be a newer model from 2008 and best with AWD. Nominally the approx. 300hp of 3.6l more than enough to me. Seriously start with the search and test drives it will only be in a few months in the spring but you can look and ponder now already 🙂 Although I believe now read all the posts here to the CTS and STS but … The CTS is about the same of the outside dimensions as the GS. If he also inside so I’d rather have living room sofas like my ’93 STS. But I don’t like the current STS like that, certainly not from the inside. There the CTS is just a dream. Sure, taste question and a question of willingness to compromise. What would interest me in advance are impressions of people who have already driven or at least sat inside and ideally can compare not only CTS/STS but also CTS/GS. Of course, I’m not interested in this. ch interested in other opinions, not only about the feeling of space, but also about processing, quality and problems – even if it is only hearsays from other forums (BTW: does someone know links to pages in German or English?). So please help with a kind of preliminary decision 😉
