As the title says, what's the point of Lester locating a car for you? It's the same vehicle, in the same place every time for me (an ATV at the race track).
I've seen suggestions that it's so that you can get a vehicle that's not stolen, but if you have to go to a specific place to pick it up then it's pointless. I may as well just go to my garage and get a car there.
I was (as were most people) under the incorrect impression that you would be able to specify what car type you were looking for, which would be great for collecting high value cars for Simeon, so it's disappointing.
Or am I missing something?
