[QUOTE=csmeance;7276224]1) BMW's operating temp is about 220-250F which is WAY higher than your typical car! I'm willing to bet your cadillac is more like 210F. This not only takes longer to get up to, but is bad for all the little rubber seals and such in the car. Us E65/66 owners are learning of this now and are figuring out why so many gaskets and such are failing.
My car runs about 105C or 220F steady state. It is cold out now we'll see where the temperature gets to in the summer. The 12 O'clock position on the gauge is 120C or 248F but it never gets there.
