Performance-wise, they are similar.

The big question with the 04S is whether the IMS has been changed. $2500-3000 if not (incl IMS, clutch, & RMS).

The big question with the 09 base, if PDK, is whether the trans fluid has been flushed. This yr requires 6 yr / 60 mi service. $700-1000 at dealer if necessary.

Tires for either would be $800-1200. Brake pads ~ $300 for parts. Check oil intervals on the receipts - you want 5-8K mi btwn changes. Esp important for the 04S since at the time it was new, Porsche & Mobil had too long of intervals.
