recently i bought a 2006 CTS 2.8L i'm a mechanic for GM and i love this car!!. and 2.8L does compete with the 3.6L, there is hardly any chance of feeling the 60hp difference other than racing purposes. which buy the CTS-v not the 3.6L or 2.8L. they are poor in the snow if not treated properly (drive for the conditions) I have a corvette as well and people who compare 3.6L and 2.8L engine clearly don't know what a real sports car feels like. or are that ignorant, to do these type of comparisons. thank you to all the people who took the car for what it is made for and not blow it out of proportion, remember it is a four door sedan with a V6 either of them 3.6L or 2.8L. all an all beautiful car
ride smootheness and exceptional handling. also both 3.6L and 2.8L exceptional engines very similar and the 2.8L is not dis-continued it is still offered in europe!. It's a caddy not a honda or a acura .
the only improvement for this car in my opinion would be to put a little more thought to the interior and not so plastic
