condition v.s. a condition

Hi,

Could you correct the sentences, please(esp. the use of the articles)

Thanks in advance

.
Your motorbike is in showroom condition
You left your room, which is in a terrible condition. (No article suggests that the room itself needs renovation)
His heart is in poor condition. (threatening is the wrong word)
He has a bad heart condition.

Hi, MM

Many thanks for your reply !

So, if I said your room is in a terrible condition, it would mean that the room needs cleaning up and
if I said your room is in terrible condition, it would mean that the room needs renovation
Am I right ?
