Sorry hear South
I wish you luck & hope you poke in here & there.
Anyway, so as not to find yourself in the same scenario, I would suggest once you have it narrowed down to what your looking for, go hang out in the dealers maintenance shop a few times seeing what cars come in there (hopefully the car you like) & talk it up with the the customers in the lounge on what their experience with the service department is like before you buy. This way you can get a feel if you are going to be happy taking your car to them.
Best of luck to you
