As a DIY mechanic, repairing and restoring cars can be rewarding. Start with basic tools: wrenches, screwdrivers, pliers, and a jack. Focus on essentials like oil changes—drain old oil, replace the filter, refill with fresh oil. For brakes, inspect pads and rotors; replace worn parts with care. Restoring older cars? Sand rust off the body, prime, and repaint for a fresh look. Engines need patience—check spark plugs, belts, and fluids. Use online forums or X posts for tips from other DIYers. Search web tutorials for tricky fixes like transmission work. Keep a clean workspace, label parts, and test-drive safely after repairs. With practice, you’ll turn rusty wrecks into roadworthy classics. Passion and persistence are key—happy wrenching!
