I'm in the same boat as you!!!
But I promised myself I will be done in the next 2-3 months after I:
- Add intake (don't really like green filter and de-snork)
- Add sport cat to replace de-cat
- Add PES flash
- Add Lotus Driving Lights...
- Multivex mirrors
That should only be around $1700
Wouldn't mind doing coilovers, GUT wing and CF canards...that'd be another $3000 or more.
