He knows that they aren't e-marked as it was only fair to tell him. he said that he doesn't really care because he believes that they won't check for the e-mark in the test, even after I explained the reason for me wanting to swap. He believes that my alloys are more in line with the look he's going for so that's why he want to swap. However, this is totally besides the point. I was just asking what people thought about 16" TI alloys, and if they were definitely replicas and is it worth the downgrade in size.
I don't believe it to be fair to burgle his house as he seems like a nice guy. Furthermore, I don't see the relevance of this suggestion. I think I'll go for the swap, thanks for the help :P
