Original warranty?

["Peter C." <nosimport@mailbag.com>]

Whilst perusing my "Austin Healey100" (happens to have a 4 cylinder engine, 
but we know that) "Owner's Handbook", I noticed the warranty disclaimer in 
the back few pages. Austin Motor Co. Ltd. clearly disavows any liability of 
many components on the car and provides names and addresses of the various 
equipment manufacturers such as Lucas, Champion, Dunlop, Smith, Girling, 
and Armstrong, to name a few.
        Fascinating.
        Can you do that?
Just wondering.
