Just renewed my 92 the other day, it was $46.50 and I paid online, no "fees", not sure what happened to you, unless it is because the car is in a different weight class.
What gets me is that I have a 69 C10 pickup and a 69 C10 Suburban and the pickup is a "truck", so it is like $75 or whatever, but the suburban is a "wagon" and when I renewed in December it was $44.50
