I personally don't see the need for layout changes minus maybe ones regarding pictures. To me it's a forum, and the written content and member input is what makes the place over any snazzy updates to the look and ease of browsing
As stated before this is one of the best online sources you can find for tech information for anyone to diagnose/seek advice from people either in the same boat/or have been through it themselves, or just someone trying to further their own knowledge of their car.
The cost of membership is irrelevant compared to taking it to a garage and letting them figure it out for you at a far greater cost. Access to hard to find 2nd hand parts and input from others over companies safe to buy from is also a bonus, add that to the potential social side here from forum events/small meets or just a online car chat.......and for the cost of just over 2 pints of beer a year less in our lives.
