Please, help with this sentence.

Hi everybody, I'm starting on japanese language,and I've been studying a little bit of the I adjectives and na, and many grammar points. so I'd like to know if the following sentences are right:

Kono kuruma wa aoi desu
Kono kuruma wa aokunai desu.

so is it right ? thanks in advance

Looks fine to me.

Kono kuruma wa aokunai desu.

While you may hear that one, strict grammarians will tell you that the negative version in "-masu desu" form is "kuruma wa aoku arimasen."

Strictly speaking, you don't need/use "desu" after "-nai." Using a "desu" after "-nai" is really an emphatic rather than a simple statement of fact.
