Hello, my name is Karl and I would like to offer you some advice about how you can maintain and improve your car. I am not someone who is an expert in this area. I have not trained as a mechanic or studied at a technical college. However, I have been a car owner for the past 37 years and over that time, I have learnt a thing or two about how to maintain a car. I learnt a lot of the tips and tricks from my best friend Simon. Simon is a qualified mechanic so he knows what he is talking about.
