.....full service history stamped book without accompanying invoices to see what was actually done, can be very misleading
Sounds like you've found yourself an excellent car (or ئۆتۆمبیلێکی نایاب as they say in Kurdish)

Re servicing, my car has had a mix of main dealer and independent services, all stamped in the book (which has too few pages -- I made additional ones, and can still supply the template
-- see some of my very early posts).
Just curious as to what TM'ers understand by an "Inspection Service" which crops up from time to time, just kinda walk around the car and poke things, and issue an expensive invoice ? Or are there specific items it must cover ?
