Regarding electronics – yes, the 991 generation is computerized, but Porsche’s reliability has been solid for the Turbo S specifically. It’s not like you’re buying a problematic generation here.
That’s a beautiful spec right there. 17k miles on a Turbo S is genuinely rare. The market for low-mileage 991 Turbos has been incredibly strong over the past few years. I’d say this pricing is competitive if the service history is complete.
