Slight tangent: it's sometimes easy to forget that everything you post is memorialized on the internet forever! And can be searched and found by anyone who so desires. When I recently sold my e46 M3 to a guy in Canada, there was a bit of a 'dispute' at the border. In short, Canadian Customs actually called me on my cellphone (I'm a US citizen) while they were detaining the purchaser and car. They interrogated me and wanted to know what websites I advertised the car on. They proceeded to log onto each site and read thru the posts and comments in an attempt to prove that we were conspiring on the declared sale price!!!! This went on for 45 minutes.
Be careful what you post.
