New Lumix ZS 15 versus used Lumix DMC-ZS7

I bought a New ZS 15 for $189 and then found a used DMC ZS7 for $150. The ZS7 seems likes it is a slightly higher end camera, as it has a GPS. It's in great condition. This may sound crazy, but would there be any reason to prefer the used camera over the new one? It's not clear to me how much I would need the GPS.

(By the way, Costco is selling something called a ZS7 which is absolutely not the same as the DMC ZS7 NOT this camera http://www.dpreview.com/products/panasonic/compacts/panasonic_dmczs7.)

I'm replacing my Lumix DMC-TZ5 DMC-TZ15 (which I lost).

Thanks!
