How bad is sitting for a Boxster? Question before potential purchase

[shadrach74]

My $.02 is that yearly oil changes mean little to nothing if the oil has 1500 miles on it. Again, what makes it look like it's been sitting? Check for leaks, examine all the rubber (belt, hoses, bushings, CV Boots, mounts, and seals). Also pull the trunk carpet and look for signs of coolant stains.

I also second Southernstar's opinion that a coolant flush is make work.
