I feel SCN is a pretty unique site, welcoming with an abundance of technical knowledge and more than willing to help. It's hard a big part to play in me having my 3rd Seat now, and is a consideration for me thinking about my 4th (and if not staying in the VAG family). I don't think other marques enjoy this (if you've been to a BTCC round where SCN has its own parking area, you'll see what I mean!), and it's an absolute pleasure to be a part of it.
Long live SCN!
