To me it actually seem more on the higher end from todays perspective. Assuming that the "13 1/2 Studio Time" is in hours not days.
What I have seen usually being quoted by professional studios in Switzerland is around $150-250 per hour for studio+engineer with discounts if you book days.
But the recording sessions are only a small part of the process from writing to publication of music. And what really racks up the cost if one starts adding big names to any part of the production. If you just stick with professionals that charge for their services, not their brand, you can actually get great productions for not too much money.
