Thats one hell of a demand. Do you think rx8fanatics has nothing else to do? Bilkul faragh samjha howa hai? Matlab you're telling him to fetch an rx8 from one showroom, x5 from another showroom, then park them side by side in his garage? And then get a photocamera and arrange a photoshoot? 
You don't need to go through all this trouble rx8 bhai..even if you do it, people will say its not even your house, and then you'll have to arrange a photoshoot of your house with its registry papers with your name on it. And then they'll say its not your name and you'll have to photograph your ID card in your hand with the registry papers in the other hand standing in your garage with rx8 and x5 in the background..
Even then people won't believe you and ask for a DNA.
