I found a 2013 P85 that is going to go through a dealer auction next week. It has about 85k miles and some cosmetic issues. Known issues are a cracked windshield and the touchscreen has a crack in it as well. I went to look at it in person yesterday and it was complete dead. The doors wouldn't open and the trunk would not close. I have learned that there is a 12v battery that is required for it to come alive. I don't know if that is the only issue or if it only needs a new 12v battery. I know there is an 8 year warranty on the drivetrain but I don't know what is covered under this. So, my question is - would you take the risk buying a MS under the circumstances and relying on drive train warranty? How much of a discount would you expect for you to buy? This will be my first MS so I don't know what could go wrong to make it inoperable. I was going to make another visit this weekend to see if I could "jump" it before it runs through the sale.
