Doyusa 1/12 Mercedes SL kit

Are they Doyusa 1/12 Mercedes 450SL and 450SLC good? I mean, I have a Arii 1/24 scale 450SLC, which is the same kit on a smaller scale and with a few less details (and missing details too). Are they 1/12 kits that much different in terms of quality (accurate shape), features, etc?

They command premium prices on eBay.

I haven't found detailed pictures of a built-up example.

Anyone who has one care to comment?

Scratch and reverse. Questions answered. After regular google searches over the past few years nothing turned up, but something just did. Lots of detailed pictures here for those who are curious:

I have the Entex version of this kit, It's not too bad. They could have molded it in a lighter color, but with very little work, it can be made very presentable.
