I am very satisfied with the order process, customer support and i will recommend yo others. Many thanks
When I ordered, there was no stock for the particular car I owned. I waited one week for the stock but had to write in to check what was the status. However, I must say the response was good.
You should send a tracking number. I ordered as express and it took 10 days to arrive and i couldnt track it.
