You mean Jap spec'd Camry & US spec'd Caprice? If this is the case, then it's not possible.
- Jap spec'd cars are RHD
- I believe you're talking about 2000+ model Caprice? There is NO Caprice for American market. after that 90's shape saboona.
- Keep in mind that recently new law have been imposed that you cannot import 5 years old model.
There are hell lots of option available in KSA, why bother with importing, exporting thing?
