Mods don't add to the car value. It sucks, but it's true. Instead make sure you have all the service done and use stuff like "got a new set of tires with only 500 miles" to up the value.

Mods are useless for price bargain unless you find someone interested in modding too and appreciates what you did. However, if you find such a person it's not guaranteed that he/she will be interested, because 90% of the fun in modding a car is the "it's my car and i like working on it" and it's no fun if the car is already heavily modded.

 

I'd say keep her but it seems your heart is set on selling. Thats not high milage on your car... but why not keep it and just upgrade your existing mods + internals?

 

Yes, you should sell it for what ever you can get for it and then buy my '99 A4 quattro sport with 160K miles for $6K. Let me know

 

try checking in ebay with similar mods...they have audis selling all the time...
also i noticed that they get sold on ebay for somewhat more than a private
sell...
