I'm totally new to own a car.
Other than change on the engine, what can void the warranty of a new car?
While keeping the warranty, is it Ok to install/change/upgrade?
- audio system with amp & sub
- keyless entry remote
- alarm system
- rims & tires
- spoilers & sidestep
- air & oil filter
- headlights
- spark plugs
- paint job on some parts of body
