Does this look like a hoax or scam?

[1986Silverado]

Got an email about an 85 truck I sold about 6 months ago and I responded that I would sell my 86 to him for $3000 and this is the response I got back:

Thanks for the mail response.I am okay with the
condition and am okay with the price wheel base 86
($3000). A client of mine is owing me some funds in
United State ($6000), I will instruct him to issue a
certifieds cashier check for you, and as soon as you
cashed the check.

You will deduct the cost of the wheel base 86
($3000),and the remaining balance will be Send to My
Shipper via Western Union Money Tranfer for
immediately Shippng Arrangment of the wheel base 86
from your location.

Do get back to me If this is okay by you with your
information (Full Name, Contact Address, Phone
Number), so that i can forward it to my Client to
issue the cheque for you ASAP. Hope to hear from you
soonest.
Best Regards,
Smith Baddy...
