Shock absorber for SL R230

Hello, my workshop thinks my front shock absorbers for my SL 500 (R230) are over. He also thinks that they would cost 800 + VAT per piece, so together 1,600 euros plus VAT. Now I have tried to get new ones over the Internet, but amazingly nobody, really nobody can deliver them. Can you help me? Do I enter wrong? Do you have a tip? Best regards TOM
