Take a close look at your tires for dry rot. They may have lots of tread life left but at 11yrs old and only 45K on them, they may be due for a replacement. I inherited a 10yr old Buick a few years back with only 16K on the odometer. Tires looked great but after a few weeks of daily driving, the rubber started breaking down quickly and the tires were unsafe to drive on. The TPMS sensor lifespan is around 8-10 years depending on where you live. Cold may cause them to go out earlier rather than later. At this age I would budget to have four new sensors put in when I get new tires put on.
Don't forget the front transfer case gear oil change. If you are starting from a known state for maintenance, get that done as well. I would also do PS fluid, brake fluid, pull the plugs and check them for any issues, also will tell you if your valve cover gasket is leaking in to the spark plug tubes. Have the battery checked as well. 4yrs is around the lifespan for a battery. Check the accessory drive belt for cracks and condition due to age not miles. I replace them every 50K as well so you are about due. Cabin air filter and engine air filter change too. Lastly make sure your brakes are not hanging up, suspension bushings not perished and the struts not leaking.
Good luck with your new ride. Mine is an 08 with over 210K on it and runs like new. You should get many miles out of your V if you take care of it.
