Actually, it's neither of those.  You forgot to get the value from the hash.

($vendor,$family,$modelhtml) = $Models{$model};

Not there yet....  This assigns the value for that key, which is an array
ref, to $vendor.  $family and $modelhtml will be undefined.

($vendor,$family,$modelhtml) = @{$Models{$model}};

This dereferences the array ref, and the resulting list is assigned to your
list of scalars.
