I did search in autolanka forum and other places too. But there are different things missing and some wrong information as well. My expectation was to let people comment here what they know so that after some time we have everything in one place. Exactly the idea of a blog as you said but also is "crowd-sourced + verified".
It would greatly help if you can share what you know instead of where to find. For a start, I will also share few things soon after compiling together the information I have.
For the price matter, you might find ######.lk can be misleading as the original price for a sale can be very different from the price listed there. I was expecting to people who have really bought or sold a vehicle to comment here so that we can again have crowd-sourced information about price point as well.
Anyway thanx for initiating the discussion.
