High altitude is the biggest reason that it would have been nice for MC to offer a supercharged engine still....... Simple pulley swap, and you are back up to full power.
Maybe, if you are lucky, you could find a good deal on 2011 X35 or X45 with an LSA. It would obviosly have more power than you needed, but you could do a 5 minute pulley swap when you go to 6000' and still have 550hp.
ok....ok.... I realize it is not very likely to find one, let alone, for less than 70k..... I was jussayin
