Startup Idea: Smart Car Tracking System for Auto Dealerships

Startup idea to develop a software solution for auto dealerships that provides real-time tracking for all the cars in the lot, streamlines the car delivery process, and simplifies the transaction documentation.

I was recently at an auto dealership and there must be a better way for them to find a car...and to make sure it's the right one. They had some board in the office that list cars/colors and I guess had a code to match with key -- 2 out of 3 of them were the wrong car when we got to them. Another issue is they have you driving around the whole lot holding the key fob out the window and hitting trying to find the car...seems stupid. Luckily it wasn't too cold. Isn't there somewhat they could see on a screen where the car is, and then drive you to it??? Everything about buying a car looks like software is needed...do we really need 10 pieces of paper -- one of them being about 2 feet long -- to document the transaction? Good Luck -- hope you can solve this one.
P.S. I would love to work for you guys -- I'm always finding stuff that I think could work better!! This is the 3rd time I've accepted this hit -- if that's not allowed, I understand but I love venting my frustrations on someone who might be able to help!!.
