I am a car enthusiast and have owned a few Astras in my time, I am not a trained mechanic. I enjoy making my information available to you via this website and try to point out some tips along the way if I can. I can't promise that anything I show you will work for your particular car, or that you won't harm yourself, someone else, your car or your warranty by doing it. Be safe, be responsible and unless you know what you're doing, do not play around with very serious machinery. Please consult a qualified mechanic if you are in any doubt.
