Searching for the word "quite" in the Vehicles For Sale Forum does not return this thread
Doesn't matter if you use the default Search Box that drops-down off the Search link at the top of the page, the "Search This Forum" from within Vehicles For Sale, or if you use an Advanced Search. Also does not matter if you search the entire post or just the title.
Using Google to search GL does return a hit. So does using the GL Search with other words in the thread, such as the word "complete".
The thread has been there for days, so I would not think its an issue of not being indexed, etc.
