I also had experience with Teseven.
As everyone I was impressed by excellent marketing (Instagram etc), pictures of restored cars, convenient forms of order and easy payment. Slightly confused by the lack of detailed photos. At the first stage I had a good impression - “plug & play”.
The second stage was not so nice: correspondence, delays, standard and non-standard explanations. In any case, it turns out that the order will be made with a several months of delay (2 months +). During this period it is expected to collect: vocations, breaks in production, a multiple promises that your body had been welded or sent to you. At the second stage the impression is greatly spoiled, but there is a hope.
Next step is a delivery. Usually performed reliably (when you have reliable information that you passed stage two - production). The impression from the delivery stage is good.
The last stage - the body itself. Unfortunately, expectations rarely meet the reality mainly due to lack Of the detailed photos of the bodies. So usually the client does not fully understand how much the body is different from the original! This does not indicate that the product is bad or the body is not straight!! Just the body as a whole repeats the form of the original, in some places it is very close in shape. But clearly, for an authentic restoration, the body and parts are not suitable at all !!
Some observations: the arches are made more for 33+ wheels; thicker metal is used; the floor does not exactly repeat the original (thick metal and a weak press); the rear sill does not go to fender corners; mounting to the frame must be done separately; no attention to the small details, curves, welded nuts and general quality of welding.
The pros: new strong body; much stronger than the original protected from corrosion; there are options to make a box in the floor; you can choose the body style (different generations - early, before 1979 or 1979+; short, medium or long wheelbase);
Conclusion: if you do not plan the original restoration; your body is ruined by rust; you are ready to tolerate the deadlines delay; you are ready to spend time in order to refine the body - this is a good replica!
