If you went on the average of 12,000 miles per year then it is quite a bit over, 25k to be exact!
The national average now though is 10,000 per year which would be 50,000 for your car, then it would be 35k over the average!
Depends how much you get the car for though, you could argue the toss that it is quite a bit over and get a good discount.
Personally i'd never get french anyway, I always go for something German or Japanese as they are hugely more reliable.
Servicing scheduals vary from different car makes. Usually it's every 12k but some cars now can be every 20k. Not every service will be a main service, they are every other year. You will have a main service, and then a small service and so on.
