2004 CTS 100,00 Mile tune up? on 2004 Cadillac CTS

My 04 CTS has 112,000 miles and I'm thinking about doing a major tune up, the dealership says it's $700 and doesn't include transmission or radiator flush. Does any one what exactly is reccomended at 100,000 miles? Is $700 a rip off? I've tried researching it on google but haven't found anything useful. Thanks.
