Meaning of よりまし in バンパー外すよりまし


A friend posted on a social network a picture of his Subaru car's bumper after
an minor accident, and got this comment:

> 大丈夫！バンパー外す **より** まし！笑

I guess it means

> _No problem! Removing the bumper will make it look better! lol_

But what is the exact meaning of よりまし in this sentence?

It's in Kansai if that matters.




**Edit.** (Thanks to naruto for pointing out the correct translation.)

> 大丈夫！バンパー外すよりまし！笑  
>  No problem! Better than missing the bumper! lol

よりまし is より ("than") + まし ("better"). I don't quite know why, but you seem to
get the opposite meaning.
