Last Friday I rolled over 180,000 miles in my car, marking my 100,000th mile of ownership.  It's been a daily driver for the past 7 years, but on Saturday I finally picked up another car and retired it to weekend/track duty.  I don't do much drag, mainly looking to get back into autox and hopefully some hpde.  
Despite being FILTHY from sitting under a tree all weekend, I took it to the track to see what it would run 100% untouched from how I've been driving it so that I have a baseline.  I'm in the right lane.
 
80% of it is probably the driver, 10% is probably the 7+ year old Sumi's that I bought used and then put 45,000+ miles on already, and the last 10% is the tune that I never completely finished.  I just couldn't launch it.
