Oh gosh this could take all night...this is my 10th season of autocrossing (6th at a National level).
August '08-- won H-Stock at the Wendover ProSolo in a $500 Ford Escort GT (all stock) by a huge margin. 1st place qualifier for the Super Challenge, ended up winning the whole shebag, only $1100 or so (no tire $$ or manufacturer $$, just payouts from SCCA & Hawk Brakes). Followed up with a 4th Place finish at the ProSolo Finale, and 16th at Solo Nationals, not bad for a $500 car--
March 2009, won H-Stock at the Houston National Tour in a "free" car, but I had about $300 into it. Re-used the tires from the Ford Escort
2007: Won almost every National Tour and ProSolo entered in my "other" Impreza, winningest H-Stock car in the country that year and was never beaten by a MINI Cooper until Solo Nationals. 2007 ProSolo National Champion (HS), 6th place Solo Nationals.
My $900 '88 MR2 Hardtop Base Model (if you know MR2's, this is the "best" 1st gen you could buy). NEVER should have sold it. Still kicking myself.
2006: Beating the reigning ProSolo National Champion on "inferior tires" and with a bit of ice on the ground-- priceless.
'89 Mazda RX-7 GTUs = uber rare unicorn car. Bought for $150, sold for $5000 after it was returned to stock.
