My 2012 v5 with ATP is showing its age. 270K miles and cracked cylinder or something. K-Seal has helped tremendously, but I know it is not going to last. New cars are almost 4-6 months around here. Not sure I can wait. Used cars are crazy, but what can you do? So, I"d love a newer "v", but we know those don't exist. I am Looking at Primes and "regular" Pri's. A must for me is DRCC and leather. What models do you recommend? Is the gen 4 touring the "top of the line"? And I believe the Prime Advanced is the top? In the Gen 4 I also see Limited and XLE?? I"m so confused..
