Where are the Cars in Sims 4 And Being Able to Customize Items?

One of the features I miss from the sims 3 (besides babies that do more than just sleep, poop and cry) was the ability to customize almost anything in build mode.  And being able to purchase actual vehicles in the game (besides boats and bikes).  With sims 4, it seems you have to keep buying packs to make the games more interesting and enjoyable. All the features EA keeps adding nor any of the packs they have put out so far have any of these desired items from the sims 3.  Seriously?  Some of the most current packs are a re-hash of the same things, or making existing actions in the game more "attractive".  Bore! How about adding cars and item customization without having to pay for it? Now that is an update I would look forward to!
