I recently purchased the complete Acela set, power pack, etc.  I actually work for Amtrak as a Conductor, on the Acela occasionally, so naturally I was excited to see the two power cars and 3 passenger cars were from the actual train.  I was even more excited to find the two add on cars, end business as well as business class matched up!  However I was wondering if you make Business Class car 3531, thats the one missing to make the complete set.  The train runs great and looks fantastic.  Thank you.
