Personally not a fan of the Ti editions as they all have the two-tone seats (not my cup o' tea).
For that vintage (pre-facelift) and price-range, I'd probably be looking at an `05-`06 Turbo or even a Turbo S.
In addition to the HP bump, the TT rigs have a quite a few niceties that are either options or not available at all on the base/S models.
FYI here's an `05 TT in the same area with similar miles for $2k less. Might be worth a look:
