I am close to pulling the trigger on a 1987 GTS with approx. 19K miles. My last concern with the car is the lack of full service records. The seller has some records but not all. In asking about the 30K service, he indicated that he had it completed but not all at the same time. Some items were changed and addressed over time. The belts were changed approx. 4-5 years ago so it sounds like they may need to be done soon. How critical is it to have the full set of records and should I be concerned that the full 30K was not all completed at the same time? Should I just be concerned over the belts at this time if most of the other work was performed more recently than 4-5 years ago? According to his mechanic, the car is tight and could most likely go another year but I am extremely concerned that due to the age of the belts, I may have a major problem. This definitely will play into what I offer for the car. Thanks for the advice and if anyone knows of a great place that works on Ferrari's in Arizona other than the dealer, please let me know. Thanks.
