Anyone here done soundproofing and ambient lighting on the Haval Classic? Any advice?

If you want to install it, you can add a starry sky ceiling decoration. As for the price, a good one with music control costs around 1500.

Save the money for a new car instead of making unnecessary changes.

If you really care about noise, change all four tires to Michelin or Sailun liquid tires. Then, switch to Shell engine oil from the 4S shop, and spray the chassis armor twice. You can do whatever you want inside the car. Tires cost 3000, chassis armor glue 500. Depends on how much you're willing to spend, engine oil is 400 each time.

How to install soundproofing? Just use soundproofing cotton for the whole car?
