See if you can find out if the altenator has been replaced,if not there`s a good chance yours might go.
I got my Max with 60,000 on it and within 3 months the alt needed changing.It`s a common fault on these cars unfortunately.
If they had serviced it,why didn`t they stamp the book?
Check the oil on the dipstick ,if it`s a light colour then it`s been changed,if it`s black then it hasn`t.
Also ask them if they changed the pollen filter.It needs changing every servive.
