Car looks ok. I would want it a little nicer underneath for 170K (shocks looks like they have been around for a while, airbags in springs seems a little half-assed, etc). Better brakes were a good plan. I highly dislike the stupid wheels. If you are going to ruin the look of a classic car, at least pick one that wasn't so awesome to begin with (a plain GN instead of a GNX). At least stupid wheels are easy to rectify.
I would prefer an unmolested GNX, but if someone wants to bring me this, I won't complain, I promise.
