UPDATE 11/20/12: Below are the parts that are still available. Prices have been dropped as well.
2) Authentic Vorsteiner Type 2 Rear Valance - $650 firm (Original price was about $850 + tax if I remember correctly)
Only has about 1500 miles on it, so its in excellent condition. PRICE DROP: $600
5) AA Exhaust- $1,750obo (originally about $2,800)
Excellent condition. (pic above) PRICE DROP: $1,600
6) Encore Titanium Exhaust - asking $1,500 firm (originally about $3k from what I recall)
Under 1500 miles on the exhaust. I had one connecting pipe custom made as the original one was damaged in shipping and titanium is too expensive to repair. Doesn't affect the exhaust in any way.
7) Rennen 20" Concave Wheels - $3,500 wheels only (originally $5k)
Excellent Condition, under 1,000 miles on the set. PRICE DROP: $3,300
8) 20" HRE 540R - asking $3,500 firm (originally between $6-8k)
Recently refinished, excellent condition. Tires (PS2) are included as a free bonus as they are old (use your own discretion here).
