its only the first one thats really out by 4000 miles, the second service is out by 1000 miles
if it was a high miler then maybe go all out service.
but most of why we service out cars every 9000 miles is to change the oil thats all.
if all the services after that are spot on, no ones going to worry about the first 2 services.
my trick also in my owner ship is to document everything. i keep a spreadsheet with receipts to back it up for every little thing i do, from changing a bulb, to having it serviced. i register the date it was done, the milage at the time, what was done and why.
i found when i sell up its a big confidence seller as the person can read it like a book everything done to the car. and it puts there mind at rest.
i did it on my 306 gti as the previous owner had done it, but never did it to the mr2 or civic. but am doing it again with the Zed.
