first, the 787 is a much more complex car overall.

Second, the 200 isn't much of a discaount because the D was sold around 220 when it came out.

Third, the base model is AA's own D Type from earlier times, which was a (rather good) 70 Euro model.

On the other hand, in today's world with sealed cheapo diecasts, costly simple resin models and hi-end cars 200 is halfway reasonable.
