Not so much of a review, as I haven't seen any parts for this model. However, I can give you some more details from some information that DeAgostini have been kind enough to provide.
The model is 1/8 scale, and is about 552mm long, 268mm wide and 124mm high.
It's made from ABS, high impact polystyrene and diecast parts. I guess there's a bit of rubber type material and maybe a bit of fabric as well !
The detailed engine can be removed from the car and displayed along side the model.
The steering wheel is removable, and moves with the front wheels.
The seatbelt is faithfully reproduced, as are the brakes and discs. The wheels are removable.
The model is endorsed by Professor Gordon Murray, one of the car's designers.
The series comes with downloadable magazine, which includes a rich editorial content covering the life and career of Ayrton Senna, the cars he drove and Racing the MP4/4. There might be a few instructions as well
Pack 1 gives you the nose cone, a front wheel and tyre, a rear tyre, the front brake and the start of the engine.
