Darren Jones was amazingly helpful. He spent a good deal of time with me before buying the Dinan Stage II download. He answered every question I had; this attention helped convince me to go for the download. If I hadn't had someone with his knowledge and customer service I very we'll might still be pondering the purchase. Can't tell you how much I appreciate his attention.

My Z4 runs like a dream with the Stage II. It performs just as Darren described. It seems to integrate into the BMW software seamlessly. I could 't be happier with Darren and Continental Imports.
