Porsche 924S Values?

[digbyx17]

Hi people, I'm new on here and after a bit of advice... I run a small garage and I sell a few cars, I'm currently trying to do a deal on a car where I take a 1988 Porsche 924S in part exchange but I have no idea about 924's!
The car is in great condition, has covered 94,000 miles, been in the same family since it was 2 years old, full service history, finished in burgundy with cream cloth. Has anyone got an idea on how I value such a thing? Any input would be gratefully received!

Bodywork is perfect, it had new front wings a few years ago as well as a respray. I thought around that figure... thanks for getting back to me.
