Thanks for all the comments, guys..
@ DasWiesel: It's the Tamiya F40. A very nice model, with lots of detail and very acurate. But on the instructions are some mistakes, i.e., some colours are wrong..
btw, I've only bought 3 models up to date, and all 3 are Tamiya's (still waiting on that Corrado of yours
). I have my eye on a Revell New Mini, the price is quite appealing (€12) and with some 18" OZ Futuras with brembo brakes I think it will be very nice.
