This is what I noticed as an Ativa owner. Inside the car the vibration from the 3-cylinder engine is definitely more than the X50. But, if you stand outside with the hood open on both car, you can see the X50 3-cylinder makes much more noise with bigger vibration. I can only say the insulation is better on the X50 but that amount of noise and vibration will really put a big question mark on the X50 in the longer term. Toyota on the other hand has been making reliable 3-cylinder engine for ages while Geely in China already switched back the X50 engine back to 4-cylinder and rumours X50 face-lift in Malaysia next year will also switch back to 4-cylinder.engine.

Usually the car showroom company adds the plate number holder for free with their company branding at the bottom as some sort of advertisement.
