Scott, I'd say the inspectors advice is excellent. That oven and range are surely not original equipment, and usually require 40 to 50A circuits; you see the problem. I would be very suspisious under these circumstances. In addition to having the system inspected, verify that proper permits were obtained. My guess is that you'll find none were (but I'm a bit cynical). Expect to invest in a panel upgrade in the near future. 60A is almost absurd for a house that size. Go with a 200A. I'd want a clause in the purchase contract that the house will be made to meet code at the owner's expense. Good luck with it.
