FYI.
Highway driving is better on engines than city driving. On the highway you are going at a steady speed, oil pressure is higher so internal engine parts are better protected and engine temperature is stable. Transmissions last longer since they don't shift as often. Transmissions only wear when they shift. As a side effect, brakes last longer simply because you go so many miles between brake applications.
On the other hand, city driving is tough on cars. You are constantly accelerating and decelerating. The transmission is constantly shifting up and down which accelerates wear and the engine idles lower reducing oil pressure and causing more wear on internal engine parts. You use your brakes more often so they will wear out quicker as well.
