Correction to my 11/13/01 Rivarossi HO post. The HO Challenger will NOT have the Allegheny Drive. I guess it depends upon who you talk to at the distributor. Lima, the survivoring corporate name is the owner of Rivarossi. They have not appointed a repair vendor as yet. Again, should an Allegheny problem occur, it's a warranty exchange during the first year of ownership. The first batch of Alleghenies is expected in December and a second batch a few months later.
