A great place to start would be with a Tamiya kit, and as luck would have it, they do a Primera, in both Calsonic and Castrol colours.
You need a lot to start with, as I find if I am ever caught on holiday and want to do a kit! The outlay for tools and paints will easy be more than double the price of the kit.
You MUST have.
Scalpel
Tweezers
Scissors
Brushes (Sizes 1, 0, 000)
Plastic glue (In bottle with Brush. Revell make a pretty good one)
Clear glue, such as Kristal clear (For all clear parts, and adhereing painted parts)
Various Wet & Dry papers (From car shops)
Then your paints. Get everyone mentioned in the kit if you can, and also a thinner to clean your brushes in.
Please spray the body, it is easier than brush painting it, trust me!
Tamiya do a spray for most colours, but you are best to use Automotive paints, as described in my article on the Subaru WRX.
Good luck!
