I used to do my own servicing on my petrol cars and I always found the hardest part was removing the tray under the engine to get to the oil drain plug and filter. I'm now too old to manage it, but have found a little garage close to me that will do it for £25 and I supply the oil and filter. All other servicing is so simple to do. Changing air filters etc is child's play, so still do this myself.
