I did read that post in Renntech correctly. One post said your company was not connected to Zeintec, and run a good company even though you were family related. Another post said you were distributor:
"As the general sales agency of the company Zeintec Suisse automotive, Z-Art is responsible for Switzerland, Austria and the Middle East. This company supplies a hard top for all Porsche Boxster models. The Zeintop, whose contours are reminiscent of the new Cayman, is equipped with a tailgate and supplied with a complete respray. The hard top is now available for ordering at a price of 3,980 euros net."
