If my car's gas tank was hit, will that be considered a total loss?

I used to own a Mercedes, but I was tired of paying an arm and a leg for repair costs, so I traded it in and went with a Mazda 3. Not only do I love driving it more, but repairs are much less expensive! Where are Mazda parts made that the costs are so much lower?

I’m thinking about replacing my car’s spark plugs myself to save money, but I don’t have a lot of free time on the weekdays. How long does it usually take to replace spark plugs?

I had my driver’s license revoked last week after an accident. However, I don’t feel like my license should have been taken away. I have a problem with my eyesight (astigmatism), which may have contributed to the accident, but my eye doctor says I’m OK to drive. Can you get around a medically restricted driver’s license?
