Selling overseas

Why does he need a broker to handle the $$ transfer? This is what sounds fishy to me...
And he is going to have to transfer to the broker anyway? So why not direct. I bought my vette in US and just did a simple electronic transfer into the seller bank . I also transfer directly to other countries and use XE which is a international transfer agency and can convert and transfer. There is a lag using XE .However, all of this needs a bank account number for the money to land
