Is a Miata a good first car?

I recently got my first car—a Toyota Camry—off Craigslist, and I’m looking to add gains that really make it my own. How much does a Toyota Camry turbo kit cost?

My Jeep has recently started shaking while driving at high speeds. I’m hoping that the problem is simple enough that I can fix it by myself. But I’m an amateur mechanic at best. What causes a Jeep to shake while driving?

Should you perform pre-driving checks often, or just every week or so? I just learned about them in my driving class but I was a little confused about how often we had to do them. It feels excessive to do them every time I drive!
