Hi, I bought my SVX from a guy in Maine that is/was on these forums.
The car had a bike rack on it. He took it off to sell the car. Im not sure if he still has it or not.
He said "The bike rack is specially ordered from Australia, as a good one for the SVX is not available in the U.S. It cost a lot, I forgot how much but over $400"
His name on here is Wocketman.

I got his email if you want it, maybe he still has the rack for sale.
Pics of it on the car can be found attached to his post here:
