After 4 years with 2 M4's I'm ready for something new. It's been an amazing car and I think I'm numb to how nice it is and looks after 4 years. I also get excited by new shiny things.
I bought out my lease that ended in August. I'm between a new M4 and an 840 as I think the payments will be pretty close with the larger discounts you can get on the 8 which will help with lease payments. I'm not in love with the front of the car, but it has definitely grown on me since it was introduced. I've looked around and there really aren't any other coupes in the price range that are as nice or give you as much car.
