Ferrari Dino GTS

A friend of mine lent me his Ferrari Dino GTS 74' - and i've been really enjoying for a number of weeks now. He has asked me if i want to buy it, WHICH I WILL DO next week. - Is there anything in particular that I should look for before purchasing??? - The car has 30k on the clock FSH, exterior and interior is in good condition and it seems to drive well.
Many thanks, your experience may help me out.

First get the car to a Ferrari Dealer or really knowlegable (on older Ferraris)mechanic and have it totaly checked out there is no difference in repairing a $20,000 74 Dino than a $120,000 Daytona. They are both very expensive!
