As a teen, living at home, with bros and sisters, the vehicle is your space. Your chums judge you by your car and how smart it is. Your automobile gives you the likelihood of privacy that you never get at home. The chance to take your squeeze somewhere quiet, perhaps, or merely the opportunity to go off on your own and experience the sea view, maybe do a little bit of fishing. Remember changing the engine, changing the brake liquid, and fitting a spoiler? Did you fit a nitrous oxide nitro kit to enhance the performance of your automobile? Did you tell the insurance firm you had altered the engine? Naturally you did.

Was your first automobile in the days before catalysts? When you might smell the nitric oxide emissions coming out of the exhaust when the engine was hot? Can you remember the chlorine like smell as you backed your automobile into the garage? That was nitric oxide. These days, with all the benzene compounds added to it, gas smells completely different. Some people say that modern, benzene rich, gas in an automobile with no exhaust catalyst gives out more damaging emissions than the reliable type, complete with nitric oxide and hydrocarbons. Remember the leaks in the trunk? Oh, you had forgotten that. Remember the way the heater leaked coolant all over the carpet? No? Did you forget that, too? Remember the bizarre noise that came from the front wheels at 75mph, but that went away after you were up to 85mph? Bizarre isn’t it, how memory works? Reminiscing is one thing, but would you really ever go back?
