What other good Volvo sites are out there for the DIYer?

I get some help here but I have seen others reference info from other sites.

What are the best ones.

 

Swedespeed.com is an active site. Arranged a little different than here.
www.matthewsvolvosite.com/forums/ (It won't let me view it from China though.)

 

I use those sites as well as 30FORTY50.com C30, V40, S60r, performance parts repairs and more.

In order to search on 30forty50 I find that I have to go to Google and type in the search bar:

site:30forty50.com "subject"

and you put what you are looking for in the quotes. Works well.
