Buying Advice New Holland TC25D

[1302]

I am looking at a New Holland TC25D with 60" mid mount mower it has 330 hr. owner states just had 300 hr. service which cost him $350. From the picture it looks clean as a pin. Any suggestion as to what I should check or look or test when I go to look at this tractor any questions I should ask about performance He is asking $8800. is this a fair price it is a 2001.
Thanks for any advice
