There is a way to narrow it down - each car should have 3 possible jack spots, so check through the list under "change car".
The Most Wanted cars also have 3 jack spots each, but those are instantly awarded when you win the cars - so 30 free jack spots
I googled and found this guide which gives all the locations, though it does take a bit of deciphering and checking the mini map for the road names.
