Damage doesn't look too bad, wonder why they wrote it off?
If it was a tad cheaper (£10k?) then I guess it'd make more sense as you could perhaps swap the Kleeman bits over into another CLK500 (one that you own or buy one for £10k ish?) and then sell it as a regular CLK500 cat-D car needing repair, therefore getting the Kleeman goodies cheap
Or fix it up and keep it as a rare 500bhp CLK, I don't think you'd care all that much that it would be recorded, so ignore my previous ramblings...
