Worth it?

[AZN_Pride]

If it was a great deal, it would have already sold.

If you just want a project, start with something that will still be worth some of the money that you put into it when you are tired of it.

With today's car scene and economy, that is very hard to do. I would rather just have fun and make something I can be proud of instead. However, my knowlege of Nissans isn't up to speed and I am wondering what would be better to look for. SR20, KA24, or RB?
