How to unretire a car?
 

I have retired my previous car without knowing that I would loose the ability to view its data. I've read somewhere that it is possible to unretire. Can anyone explain how to do that pls?

It can be done and I have done it but cant remember how, I seem to think I found
the retired vehicle in the lists, they are still there and there is a button to un retire it.

Sorry, I just noticed this post. I unretired your retired vehicle for you.
