gadia is feminine, in that case wouldn't it be bechathi?
Our subject is Raj and Raj js male, so it'll be बेचता है. गाड़ियां is object in this sentence.
It could be vehicles right ?
No. Vehicles would be वाहन
P.s. वाहन is sing.
It should be sell cars right?
Good point, but "Raj sell cars" is not a correct sentence in English.
