This is my question too really?
If i dont have my service done at a ford dealership will it affect any warranty
And also, how much does a FFSH stand for nowadays?
I have checked and as long as the garage use Ford Official servicing parts the warranty is not effected.
As for FFSH I don't know but FSH is always handy as long as you check the stamps are not made up and the dealer actually did the work.
It also depends on the car I had a Rover Streetwise great little car but the resale value is quite poor so I serviced it myself which over a 7 year period saved me a lot of cash which when I came to sell I didn't lose much about £400 over a FSH car.
