That's a very nice car. I see it has lights, always a great feature and on a Scaley, you don't pay extra to get them, being forced to buy a digital car you may have no use for if you want the lights to work.
Question- Does that magnet pocket just ahead of the rear axle serve as a reinforcing item where the rear of the chassis has a narrow point, presumably to correct the problem you mentioned in the Porsche? I mention it because it doesn't look like the usual form of a magnet pocket.
