Right now, the dealerships car lists are a complete mess. There is no order in either price or name, and that makes it dificult to find a car even if you know the name.
My sugestion is to be able to sort the cars into 4 orders:
(name)
A-Z
Z-A
(price)
Lowest-Highest
Highest-Lowest
Even if adding all these 4 options isnt feasable, just sorting alphabetically in a A-Z fashion will make it much easier to look for a certain vehicle.
