This was sold as a Lexus RS in the United States.  This may help you find
what you're looking for.

That said, there are likely other problems with it - airbags may not work,
mildew may rot the upholstery and carpet, and you'll likely be plagued with
endless electrical problems.  There's a reason insurance companies total
flood damaged cars.  Unless you have a compelling reason to keep it, you
should consider doing the same.
