V12 versus SL55 V8 Longevity?

Who has an opinion on whether or not the SL600 would be a more solid car over the long haul?

Does the V12 deliver the power with less stress on the motor than the V8? Is the SL600 more heavily reinforced in the drive train?

Any one with a mechanical insight care to comment?

2004 SL55 AMG
ChrisB:

When I was deciding between the SL600 and SL55 AMG, I asked the exact same question on reliability from a veteran Service Advisor @ Keyes European here in Southern, CA.. Specifically, I asked about the service history of V12s vs. AMGs as well as recent activities. In his opinion, the relative reliability was equivalent as the latest engines V12TT or V8K are very well built. He did mention that the V12 would be a little more expensive in service costs although both (at that time) had the same 4yr free maintenance. From the SL55 AMG perspective, I haven't had a single hiccup or disappointment with my vehicle-completely solid.
