Oh dear, I can see a little confusion here.

The SCX Volvo is actually a 850 model which is ok as a Event 2 Super -Touring car (like mine). The Volvo 240 for the Event 1 is an earlier model.

As Kevin said the Megane is an Event 3 entry car as its a Silhoette Touring Car from the French Touring Championship (like DTM). If you can clearly see the interior inside the car it would be just about permissible, but from the photo it looks very dark.
The Ford Falcon is fine for Event 3 as a Muscle Car, and sounds more advanced than the Megane.

So you would need to think about a different Event 1 Car if you have time.
