I noticed another oversight... The Maserati Levante has red seats when using the on-track exterior views (and possibly in Photomode), whereas cockpit view shows the grey seats also seen in the main menu, including Forzavista. I scrolled through every factory paint option and none of the options seem to come with the red seats seen when driving the car using exterior views. I started out by giving my Levante the champagne-esque factory paint, but I would be surprised if the glitch is tied to specific factory paints.
And of course, there's at least one car in the pack for which it was forgotten to enable the shifting animation. I noticed this on the Porsche 906 Carrera 6. Amazing how Turn 10 keeps repeating this mistake month after month.
By the way, my favorite driving machine in this car pack has to be the Ferrari 166 Inter Sport.
