I have a 2010 CTS wagon. 3.6 AWD. With stock 18's. I have a chance to pick up some 20's for a pretty good deal through a friend. Unfortunately they are incorrect bolt pattern. What are the thoughts on adapters from the 5x114 to the 5x120? Also with the 20's having a 40mm offset and then adding an adapter, will the wheels stick out? I've tried to look into offsets but unfortunately couldn't come up with an answer.... appreciate any and all help.

Here is the label from the 20's

Buy a wheel that fits correctly.

A 3/4" thick bolt-on adapter is going to reduce the offset by 19mm. Stock wheel is 18x8.5 with 48mm offset. A change of 27mm will put the tire close to the fender.

I have had bad experiences with spacers in the past, so I wouldn't recommend an adaptor of any kind. Buy wheels that fit the car.

Thanks for the replys. One of those "I just need someone to tell me not to" situations. The search continues!

Much appreciated!

There's absolutely nothing wrong with using spacers/adapters, unless they're cheap and/or installed incorrectly. However, as FunkZ pointed out, a +40mm wheel with a spacer adapter is going to push those wheels out an inch or more compared to where the stock wheels sit. It certainly could be done, but if you're looking for a quick, bolt-on install with no issues, then find another set of wheels.
