I have the same. Just armrest and little bit on brake pedal when I stopped on traffic light or else. That is really annoying for me.
One of the training sessions I did while at GM was on NVH, "Noise, Vibration and Harshness". Most every car maker does those now as consumers see vibrations and noises as problem. (and they should). One of the things that you have to deal with is "what is a normal vibration?". This is important as you don't want to spend hours of time trying to fix something that is "normal". There is no way to remove all vibrations from a machine. The goal is to reduce vibrations to a level that is acceptable to a normal person. In a running engine in your V you have four pistons that start and stop about ten times per second per cylinder. This makes the engine block move around. Engine mounts can reduce the perceived vibration to some extent but some people are very sensitive to even that low level.I notice some vibrations but nothing out of the ordinary for a tiny engine. Would you consider the vibrations excesssive? I can say that in my car I don't consider them excessive.
