I assume there's no maintenance records from the previous owner. The typical thing to do would be to replace all fluids if the dealer hasn't done so. Check radiator hoses for drying and cracking, take a peak at the brake pads and air filter, look for kinks in the chain. Put a meter on the battery, it should hold a charge between 12.5 - 12.8 volts, it could be the original battery, my '09 is still running on the original, I want to replace it before it dies. Check valves.
You may want to get an Eastern Beaver headlight relay. A typical problem is the headlights stop working because of too much voltage going through the starter button. Easy install, it won't fix the problem, it prevents it from happening, so don't wait. Stators have been known to fail, some very early and some never. My '09 has 75K miles and hasn't given me any problems.
