Bit of a question that I have always wondered. Why do people service their car just once a year? Tbh I don't know what the service intervals are on my s4, nor do I care as I do bits at staggered intervals throughout the year. Sparks one day, oil another, filters, etc. While some stuff good to do together, most don't need to be. I like to change and fix as an on going thing.
What do you guys think? I could be wrong, but I like working on the car giving it plenty of TLC.
