Unfortunately, once all permanent teeth have erupted (generally around 6-7 months of age), there is no way to definitively determine a dog's age. The best that you can do is closely examine all teeth for any evidence of tartar or dental staining. While trace amounts of tartar and staining may be present by 18 months of age, more significant tartar accumulation would be highly unlikely. If the seller has any previous vet records or vaccine certificates, these would also help to prove her age.
I understand your concern about lifespan as well. As a larger breed, German Shepherds generally live 9-11 years, but in my opinion, the quality of that life and time together is even more important than the quantity. :-)
