just had a look on Revell site, and notice the are planning a 2CV in 1/24. Wonder if it is the same one as Airfix/Heller. One useful feature Revell have is having the instructions online, giving you a clue about model and complexity. It is also possible to pick up on old releases as instructions tend to be old style(and non colour)
One model which might be fun is a Surfite vehicle. Wonder if with a small rail chassis you could transport surfboards by rail!
