I have done every single item the maintenance schedule call out for. Minus the fuel pump.

As mentioned if you keep records aka receipts of what parts you buy it's the same as dealer service history.

The only thing that might affect it, is if you trade it in or some picky buyer wants a Carfax report. But any knowledgeable person or mechanic can know the difference from a neglected and a proper serviced car.
