So I was looking into buying, an x type at first, but the things that changed my mind are, that the transfer case can fail between 50-80k kilometers if driven hard (also no rwd) and that it isn't that comfortable for a person that's 1.90cm or more. So I did the next most logical thing and went looking for an s type and right off the start I eliminated the 2.5, 2.7 and 4.0 engines, then I eliminated the pre interior facelift models and was wondering which engine is purely more reliable the 3.0 or 4.2? If you send any modified exhaust sound clips of both engines, I will really appreciate it.
