Within minutes of odering on-line, Mark replied to confirm shipping. I was debating ordering some more parts and asked his opinion by email. He gave me loads of free advice on what was best for my NSX and the email exchange continued all through the weekend. What impressed me most was Mark's knowlege about getting the best bang for your $. He certainly did not try to push me into buying something that would not meet my expectations. Everything in my order arrived promptly in great condition. I will certainly do more business with Dali Racing.
