excellent car but tire problems
 I am leasing the 750ix for one year, excellent car inside out except the run flat tires I have to change 6 tires and one rim in one year you have to buy the tire insurance otherwise you are risking too much.Fun to drive almost perfect except dealing with frequent dealer visits to change tires. If you talk to their customer service about the tire problem they refuse to deal with the problem. I personally know many BMW car owners who have the same problem of frequent tire problems.This my last car with run flat tires very disappointed it is a waste of money, time and resources(rubber).
