How long [STRIKE]have[/STRIKE] has your car been out of order? (present perfect) Or
How long had your car been out of order? (past perfect)

such as: My friend and I friend are talking. My friend says :I had my car repaired. It's working now. I ask: How long have/ had your car been out of order? My friend replies: It has/had been out of order for two weeks

That particular paragraph is better thus:

My friend and I were talking. My friend said, "I (have) had my car repaired. It's working now". I asked, "How long was your car out of order?" (or:" How long had your car been out of order") " My friend replied, " It was (or: "had been") out of order for two weeks".

Actually, I don't particularly like 'out of order', but I can't at the moment think of anything better.

I would like to say it in present. My friend and I are talking now. Not in the past. Not we were talking.

My friend and I are talking. My friend says, "I (have) had my car repaired. It's working now". I ask, "How long was your car out of order?" (or:" How long had your car been out of order") " My friend replies, " It was (or: "had been") out of order for two weeks".

Yes, but the car is no longer "out of order".
