None of the Policar F1 models are supplied with a magnet. I run mine on a wood track so a magnet is pointless but with F22 tyres they run very well and all the releases so far are pretty closely matched. I use the Policar metal replacement rear wheels but I have been told that the plastic originals are quite good.  

You will need to make sure that the gears in the Policar gearbox are kept lubricated. Silicone grease seems to work but others may have better suggestions.
 
 Unusually for Policar it seems there have been a lot of quality control problems with the Ferrari which is a real shame. From reading other forums common problems are :-

The axle stopper is loose on the rear axle which means the gears don't mesh correctly. If you try to run the car with the stopper loose there is a good chance you will damage the gears.

The exhausts have been fitted wrongly and drag on the ground.

The rear wing droops because it is fitted incorrectly  

Screw holding the motor into the pod is loose

Rear axle tight - probably because axle stopper has been wedged against the side of the motor pod - it needs a tiny bit of play or a shim between pod and axle stopper to run smoothly.

Front wheels not touching the track which can probably be sorted by adjusting the braids

Front axle binding

Front wheels falling off because the axle is too short.

Unfortunate that there have been so many problems because Policar make great cars although I am sure Maurizio will get the quality problems sorted.

If you don't feel competent to take the body off to sort out any problems it would be a good idea to speak to the dealer where you bought the model. Ask for replacement and ask them to check it over before they send it out. Under UK law a product is meant to be fit for purpose and unfortunately it is clear that some of the first batch of this car are definitely not fit for purpose straight out of the box.
