Yes its a good deal, IF the machine is in good condition, and it has all of its attachments, and the hose and PN are in good shape.
Remember that some of the original hoses sold with the UltraLux Classic were the older, braided type, and will leak air like a seive sooner or later.
IF the hose is the newer, plastic "Saran Wrap" type, you should be good to go,as long as there are no kinks,holes or smashed in areas.
Make sure the hose in in good solid codition with no leaks, bends or holes.
A hose in good condition is a very important part to an Electrolux such as this.
As is the Power Nozzle, and its brush roll. (If you are using it for vacuuming carpets)
A good way to tell how much use an Electrolux cannister has had, is to examine its brush roll and PN and its wheels for wear.
Also examine the machines wheels, and open the bag chamber and examine the inside without the bag. If there is a heavy coating of dust on the inside of the bag chamber, chances are the machine has had alot of use. And/or non genuine Electrolux/Aerus bags were used.
Also, With the bag door open, and with NO bag in the chamber, hold the bag indicator button (the button on the inside of the cover, that pushes against the bag when its installed, when you close the bag door) down, (push it in and hold it) and turn on the machine.
Listen carefully to the start up, and shut down of the motor. Listen for any whining, screeching or unusual noises,,,especially in the wind down after you shut the motor off. (Do this by letting go of the bag indicator button, because this will test the Automatic Control. When you let go, the Check Bag Indicator light should come on the second the motor shuts off.)
(Any screeching,whining,or unusual noises indicates motor and or bearing trouble,,and heavy use.) May need a new motor or at least motor service in the near future.
As for re-sale value after you have used it,,well, its a big question mark. You MAY be able to get your money back, maybe not. Just depends what someone is willing to spend.
IF the machine, its hose, Power Nozzle, and attachments are all in A1, shiny new pristene condition, with NO blemishes, dings, dark spots or signs of use, you should be able to get your money back easily.
