Option lists?

If you build a car in tycoon mode, with many interior features like (I don't know if these are accurate) a full entertainment center with television, heated seats, electric everything, but it costs a lot of money, will the customer be forced to buy the car like that? Or will they be able to see an options list and choose from the options you picked in the first place?
It seems to me that some people don't need all the options, and just want the car at a cheaper price. Will this be reflected in the tycoon mode? Don't know if this has been asked before, but I couldn't find anything.
