Here are your negatives.
You live in SOCAL, where Boxsters are plentiful and the economy is now tanking.
You live in Poway, which is a ways out from SD for guys to look at cars. Too many closey by.
It is coming on winter, which even here in SOCAL, is a downer for sports cars.
You car is modded. Some purists won't even look at a modded car.
My suggestions
Look at BB
Look at the Comps-use auto trader and find cars that look about comp to yours. Figure out the price range. Keep in mind, this is the Ask price. The actual sell price will be lower, likely 1-2 grand.
Make sure the car is impeccable when seen by buyers. Prepare prepare for the sale.
Good luck.
