If someone wants to tackle such a project - maybe my Blog entry might be helpful. This does not include some more items I got this year and I still need to finish the interior.

My opinion: C6510 will be even more work than my Morgan. I would not pay more than 5000GBP for it.
The other one on EBay is off the charts. Some parts will be even harder to get. 3000GBP would be still quite expensive
