The Wald bodykits are really a step up from the normal "Barry" stuff.
This isn't a bad price for the kit, it's about retail on the stuff.
It is something we are looking at bringing into the UK from 2008. At the moment we specialise in Japanese wheels and these truely are a cut above the US/EU produced stuff.
The problem with bringing in goods from Japan is the import duty, and the need to air freight the stuff in. A bodykit is particularly bulky so the costs of transport are quite high. If we sea freight the goods in it takes up to 3 months, and though cheaper, no customer will wait that long. In addition the older models operate an exchange process on the kits e.g. W124
I have no experience with this dealer on ebay, but I do know they have changed their name recently.
Wald have started to branch out into supplying bodykits for a lot of non-Merc cars, it's a market we're very interested in.
