Ideas to make vehicles more relevant in a closed world.

I love the idea of other sims judging another sims car lol.
I would love the DIY car back (was TS2 or 3 we had that in?) but instead we have different types of car to pick from so we could have a super cheap car that is super slow or we could do up an expensive car and be the talk of the town (of course these will come in different colours too). OR we have to start with a cheap car to do up but as we level in repair skill we can unlock upgrades that allow us to update and change the cars look to the expensive car!
Would love to have something new for the repair skill, getting bored of using the wood bench.
