If you want something new, then try it. I personally do not like the 1M enough to consider at all. But I'm already thinking about trading my M next year for the new Jeep GC SRT8 because I miss having a high performance SUV. Do what you want, nothings permanent. Just do extensive testing (if you can) before you buy.
