Are there going to be constant part updates? (SUGGESTIONS)

I am still waiting for some parts for the S15,

at the moment the only body customisation you can do is body kits and wings...
and im sure this applies to some other cars too.
want to see some, front bumpers, skirts and rears. tail lights etc..

and some suggestions for future car updates: I dont think ive seen these in NFS before

-Mitsubishi Evo III

-96 Subaru Impreza WRX

-Nissan Skyline r33

-Nissan Silvia s14

-Mazda rx2

-and an ACTUAL Nissan silvia s13, not the 180sx/240sx

Some sound updates would be awesome:

- there are many turbo's to choose from, different sounds for each would have been a good idea

- or just being able to choose a blow off valve or something

- the sounds when the wheels are spinning are getting repetitive

being able to remove parts after youve installed them would also be a good idea. I might be wrong but at the moment after I install something a bodykit and want to go back to stock without changing the whole car back to stock so I can add a splitter or something, I have to remove all customisation including spoilers, exhaust, mirror etc
