OK guys I have a question for you.

What do you think of Cadillac lifespans? And by that I mean mileage. For example: I know my Mercury Milan has the potential to last to 175-200k miles while being properly maintained. (Same would be said for a similar Fusion)

What would a CTS be able to handle? An STS? An SRX?

Just wondering, thanks for the advice. Be honest I don't own one you aren't going to hurt my feelings.
