RYGUY- your car is really nice and may well be worth more than the guideline suggests. I have 9 documented 4S sales that conform very well to the formula, including FOXMAN's C2S, which has similar mileage, factory aerokit, mint condition hollow twists, 4 new tires, painted hardback seats (re done in Germany for $5.8K), and about $14K more in additional updates/upgrades, including a split-grill. The paint is 9.8 out of 10. How much better does it get? I can tell you it didn't sell for more than ask.
