Welcome. I am sure you will find lots of information and advice on TM.
I also recommend the MSCC - you will get the monthly mag to see what dealers and private sales have to offer. They will also put you in touch with your local centre where they will be happy for you to pick whatever brains they may have. This is what I did before I got my 4/4 sport and it saved me a lot of hassle (and money!). You can join online.
