Hi my names Dave. I am a 17 year old and I do not have a car. I joined this website so I could inform myself and learn more about cars so that when the time comes and I have the money I will be able to modify and fix cars with a good knowledge of what I’m doing. I have taken auto class in highschool and know most of the basics with fluid changes, brake rebuilds, suspension replacements etc. I don’t want to be that guy that buys a car and thinks he knows what he’s doing only to end up ruining his car by doing things himself. If anybody has any suggestions on articles or books that I should take a look at to inform myself more on modify/tuning cars or more advanced vehicle maintenance and repairs I’m all ears. Thanks for reading!
