Car timing, both in the shop and over the vehicle's life. How long common repairs and services take — oil changes, brake pads, alternators, transmissions — with realistic shop-time and DIY estimates plus typical cost ranges. And the ownership side: how long car batteries, tires, brake pads, and engines actually last, how far you can really drive on empty or a donut spare, and how long DMV processes like registration and title transfers take. Answers compare by vehicle type and method so you can plan repairs, replacements, and budgets realistically.
