LOL....his talent level IS Wren's business and since it's THEIR playground (and rules), either he abides by their rules or goes and finds a new place to play. There are two reasons they don't sell to the public. One being they honor their relationships with their retail clients and agree not to sell direct to the public or they believe that this repair should be done strictly by their licensed and trained professionals. More than likely they didn't cave into his idle threats and sell parts to novices or people with 4 year old engines demanding they violate their rules merely for his benefit.
It still has nothing to do with Spain's economy, lol.
