Trade my 1929 Model A for a Hummer or for a Silver Shadow

 What should it be?  Trade my 1929 Model A for a 2004 Hummer or a '71 Silver Shadow.   that's a good question.  One I have been deliberating for a few days.  The jury is not in yet but could be this weekend.   If you have any thoughts please let me know.  Or I could just hold out for a very reasonable $20,000.???
