Well, to make a long story short, he didn't know how to drive a manual, and just pushed the stick in gear. Of course, he broke something. I didn't know what, so the next day I got AAA to come have a look at it and take it to a garage. Well, it wasn't anything he could fix, so we drove the car to Annandale, to a mechanic my neighbour could communicate with (he's Korean).
In the meantime I got to drive one of their cars (they have two). I bet it was inconvenient for them, but I needed to get around. Well, the good news is that I have my car back :) The cable between the stick and the gear was broken and they had to order parts, which is why it took so long. At least it wasn't the transmission! THAT would have been expensive. My neighbour was very sorry, but you know, I should have told him. I just didn't think that people no longer know how to drive a manual. He paid for the repairs, so I am not out any money, just inconvenience. I am still on good terms with him. I told him, that next time he need to get somewhere, I will be happy to drive him ;)
