One has more miles, but is a newer model (slightly).l wo not be driving daily, this is just for occasional use. Any ideas?

Buy the 9-3 convertible, no doubt.

the listings r both closed or removed. l assume from the earlier answer that u were looking at a Cabriolet & a hatchback or sedan model. Which year+model were these cars? Although mileage is important, u should have the car checked out by a Saab repair facility. This will save u a money & hassle. By the way,this is a big must that u find a good repair facility that works on SAAB only. Only Saab repair shops will spend the big bucks ($7K-$10K) to get the necessary tools & documentation for diagnostic, servicing & repair of these Saabs.
