Dear fellow car owners, is it necessary to do full car sound insulation for the Vito if it's primarily used for family and for its large space, and only goes on the highway less than 5 times a year? Also, how can I modify the interior for better cost-effectiveness for family use?

It's not necessary to modify a car that's purely for household use. You can always do it later when there's a need.

Aren't you afraid that in the cold winter the water temperature won't rise? You can buy it, or search on TikTok for M274 engine failures or Mercedes engine failures. Then you'll decide whether to buy it or not. I can introduce you to some real owners who have experienced engine failures. You can ask them for their opinions.

It must be changed.

Soundproofing is a must.

If you don't modify your Vito, you might as well push it into the sea. 😄

Completely dismantled and modified for household use!

There's no need for that. At most, you can get some aviation seats and wooden flooring. The rest is up to personal preference. Don't ask me why I say this—I've worked long hours at a commercial vehicle modification factory. 💡

It's best not to disassemble, otherwise the noise will increase over time.
