I have just bought the car and although it had a service history. If you look at the belts from the external they seemed okay. When taken off you can see the cracks on the belts. This could be leading to a brake at some point. Rather than being stranded at the side of the road I decided to replace them.
I hope the advice helps you to check yours and replace if needed. keep your Eunos Roadster on the road.
