Changes to Car Customisation

Could it be changed so that the customer can see a catlog of how customisations etc would look on their vehicle, maybe we sit in the car with the mech and we are the ones to choose things, not the mechanic.

Once we have chosen, we could submit it -

Then the mechanic gets to work adding things, respraying, changing wheels etc.

It will save a lot of the awkwardness of last one next one, and ppl rushing because its just awkward for everryone involved.
