Conclusion:
Sonnenland offers technically superior quality, durability, and perfect fit – ideal for sustainable restoration.

Attention!
Our convertible tops are manufactured exactly for original frames and must be installed exclusively by a professional upholsterer. We do not assume liability for damages caused by improper installation or by deviating dimensions of retrofitted or modified frames. Already glued tops are excluded from return.
Note:
On some vehicles, the soft top cover fits too tightly and, despite the large adjustment range of the frame, is not sufficient. This usually affects Spiders that have been welded in the area of the A-pillars/sills.
If the vehicle was lifted without removing the engine, the body often warped slightly into a “banana shape” and was fixed in this form by welding. Even a few millimeters at the lower area can easily add up to 2.5 – 3 cm or more at the windshield – a dimension that cannot be compensated for by the fabric.
