More aeroplanes, anyone?

I am absolutely amazed. After I found the Harrier Jump Jet earlier on today, I took some time out this evening to look through other plane auctions - here there are

• 3 BAC 1-11 Airliners on sale for a cool US $4,995,000.00
  
• A lovely Cessna - described as "A Classic 1959 Cessna 310C Full IFR, Ready-To-Fly"
  
• A 1968 Cessna 421 - the description reads "Stryair Inc. has owned this aircraft N1421U s/n 0046 for over 4 years (I have the paperwork to prove this). The retail N.A.A.A. value is 174,400 U.S dollars, with the wholesale value at 140,000 U.S. dollars. Stryair would love to keep this bird, but it is necessary to let her go."
  

Wow. I am astonished that transactions like this occur on eBay.
