Jamo,
Yep, it is 1/24th. It is the best kit available. It builds up pretty nice, but could use some additions to make it more accurate. There is a comp kit available right now, but most of the stock goodies are there. There is a standard street dash in an earlier kit (red with no hood scoop). It's tougher to find, but not impossible.

You probably should just use the whole kit as it looks like the wheel wells have all been cut out as well on that diecast.

If you really want to get nuts, there is a really nice engine in the Revell Monogram Torino Cobra.

Your car is polished arruminium with different polished arruminium stripes, right? Use Alclad paints if you want to make a model kit paint job to look like your car. Licence plates are pretty easy, too. Take a photo of your plate shooting it straight on, and then change the size digitally untill it is the right size.

Stay away from the Fujimi Cobra kit - it is pretty horrible.

Warren, The parts you need are:
34 inner front wheel x2
35 inner rear wheel x2
82 front Halibrand x2
83 rear halibrand x2
84 knock offs x4
200 front tyre
300 rear tyre

The chrome on the kit wheels is not a good representation of most rims - soak the wheels in pine-sol, Whestleys Bleeche White, brake fluid, or Easy Off to remove the chrome. Paint with auto primer (I use Plastikote sandable white) and paint to match your wheels. Alclad paint is good if you have polished or magnesium wheels.
Hope that helps,
Steve
