If I had the $ to spend on an 850 (and I would love to have one) I wouldn't do it. I'd spend it on a Nissan 300zx Twin Turbo and spend the rest of the $ to restore and mod it to the hilt. I estimate that with a $20,000 budget, it is possible to build a 600 crank HP 300zx. Price of the car included.
Porsche who?
Adjust your mirrors as you see fit. Everyone has a different seating position and height. I find that they are more useful if I aim them outward (so that I can see just a little bit of the VX). The round stick on convex mirrors I have do a great job in minimizing the blind spots.
