Guy coworker whom I work with he is married we happened to talk and I ended up telling him that’s my brother fixes cars and he fixed mine?

So he kept asking if I can ask my brother if he can fix his car, and I can continue on why would he ask me this I feel like it’s a little weird, he never mentions his wife kids also
