Number 1 .. thank you for respecting me and calling me brother , but at the same time thats very rude that you are asking me to shut up .
Number 2 .. do you know what i drive 
Number 3 .. yes i am very much familiar with these types of projects and also know the very core reason why people do it .
Number 4 .. i see that you spelled Rotary correct this time 
Number 5 .. a Rotary engine can last as long as the owner wants it to
have a nice day .
To the seller "Good luck with the sale"
Bye.
