新車と中古車どっちが良いか？
Which car is better ,brand-new or second hand?

もし車のコンディションが良くて、綺麗ならば、中古車の方がいい。
If the condition is good and clean,I will choose a second hand car.

国産車と外車どっちがいいか？
Which car is better,japanese car or imported one?

彼氏が車を買うのだとしたら、国産車がの方がいいよと勧めるかな。
If my boyfriend buy a car, I’ll advise buying a japanese one.
Because I’ve heard that japanese cars’ maintenance fee is cheaper than imported cars’.
I think it is economical and easy on the wallet.
