Help with っぽい

[trin]

Hello there, everyone. I am new here and I am studying Japanese and I need help. I studied how you attach　っぽい to the stem form of verb and adjectives, and nouns to basically add "ly" or "ish" to the word. Below is a sample sentence to see if I got it.

あの黄色っぽい車はいくらですのか。
How much is that yellowish car?

Thank you so much for the help.
よろしくお願いします。

Hi trin,

黄色っぽい is perfecly OK but
いくらですのか should be いくらですか
