Warranties can vary by dealership as well.

The dealership where I bought my Mazda over the summer offers a lifetime powertrain warranty on all new Mazda’s purchased from them. That’s one of the reasons I chose to go there instead of the other dealerships in my area.

Aside from adding on different features/accessories you can’t really custom build a Mazda like you can high-end car brands.

If you want a black grill you’d either need to go with a different trim or look into aftermarket options.
