What is my car worth?

[LaunchHard]

1993 Talon Tsi AWD with 6bolt/4bolt combo (will add pics if necessary)

Owned my Talon since 2006. I have a friend that is interested in buying it but i really have no idea what it would be worth on todays market. I bought it nearly stock and have done all the work on it since. I have listed the parts below.

It made 400awhp at DB 6 years ago or more. I have had no major issues in the last 4 years and i have put miles on it every year. The car has has been quite reliable, especially for a DSM. Please let me know what you think it could sell for on the open market, however i already have a buyer.

Let me know if you need additional information. (this was the list i sent him so disregard any unnecessary info)
