@ 30k miles does the cs require the engine out service(like the 355)? back in century city for a few days and will be checking on a few cs's in the area. maybe one can come home with me(on a truck ).
If I'm not mistaken, doesn't the 30k require engine out? Even the 360 with an access panel requires (ok, probably better wording is strongly suggests) the engine drop - it's the 15k with just simple belt and tensioner replacement that can be done in the car, but aren't cam seals and a few other things needed on 360 and CS at 30K which requires dropping the motor?
Had a 30K service done on my '99 360 -- no engine removal necessary and the CS will be the same for that scheduled major service. Of course, there may be situations, as with any other car, where major mechanical work may necessitate engine out service.
