buy your sailplane scam?

Wings and Wheels has a warning on it's classified page:

Warning !
If you receive an email similar to this example
it is a scam
"Hello,I Am interested in buying your advertised ads for sale {JANTAR
GFK SAILPLANE} that been posted on the ad 2004 i am a seller that buy
items and resell so want to buy your JANTAR SAILPLANE. I will like to
know the actual price you want to offer it for sale and the present
condition and the pics of it.and mode of my payment will be a cheque
drawn from an UK bank. Note that the shipping will be handle by my
shipper that will come to you house for that pickup,if this is okay by
you i want you to get back to me with your full name, your full contact
address and your full phone number. best regards Smith."

How is this scam supposed to work?

I'm getting some interest on a glider I'm selling from someone who's
emails look suspiciously like that above. How does this work?

Thanks,
Matt
