Hello!
I really discourage you to take part in this bid. I know the seller. He is the guy who sold me this model in March. I payed him 150 EUR, but he never sent it to me, I made a bank transfer so I could not start official refund process. His nick here is 'frutbal', he is also known as paulsmodelautos. After few months he wanted to sell me this S5 again, from other e-mail address - audi-modelcars. This is why he doesn't show us the number of the model. Because it is the same piece as before.
I know you may not believe me, but I just warn you. It is quite a lot of money, so it would be sad to loose it. I lost 150 EUR.
If you need more info, send me PM, I will ask for all questions.
Regards,
Piotr
