2007 Porsche Cayman with 91k mileage for 19.5k?

There's a 2007 Porsche Cayman 987 for sale in my area with 91 000 miles on it for 19.5k plus tax. Comes from a dealership with 20,000 miles/3 year warranty on the drive train and electronics. Also comes with 2 sets of rims/tires.

I was thinking about picking it up as a secondary car, currently daily drive a 2017 Hyundai elantra which serves me well. I'd primarily use it as a fun project car to enjoy with my dad who's always wanted to drive around in a Porsche but never had the chance to and drive it during the summer, and store for the winter (Canadian).

I understand that an older German sports car will inevitably cost me a fair bit in maintenance and upkeep, but I'm moreso concerned about the potential of a catastrophic failure that would make the car junk.

Does the price sound reasonable? It's the availability of a warranty that makes it seem appealing even though its got a fair bit of mileage on it. First time buying a used car so I'm a bit nervous.
