From time to time, it is very important to give your car a once over. On a daily or weekly basis you should be checking the fluid levels, tyre condition and tyre pressure but ideally once month or so you should have a really good look around the car.
Look for any damage to parts body or mechanical that you had not noticed. If it has damaged the paintwork, then you may need to get it fixed to avoid rusting. Also, check that it has not done any mechanical damage, for example, if there is a kerbed alloy wheel. Take a look under the car, it is very easy to miss corroded brackets causing your exhaust to hang low or heat shields that are barely hanging on. Often if you can pick these items up quickly then you have a good chance of being able to rectify them before they become any worse.
