Here is another suggestion I've used w/ good success to find info about a members car for sale as for some reason some sellers just don't include much or any info about what they are selling .
Most members feel compelled to post something about their cars , either good or bad & how to fix it , so if you go into their "see all posts" option on their home place , you may find out about their vehicles past including one that they might be selling . This can include info they may not want to share w/ a buyer but in reality the buyer deserves it .
Just recently I used this approach on a SRT6 whereby afterwards I realized why the seller may have been closed mouth about it which deleted my interest in buying .

I hope this post doesn't eventually eliminate this option !
