Free winter bikes for new Swift?

Hello, a friend of mine has had an offer for a new Swift 1.3l (92PS) Comfort made. The seller offered her a set of winter bikes as a discount. Is there currently the winter bikes with every new Swift ex factory and she can also get a discount from the seller, or does the dealer give her the wheels at his expense? I read something on the Suzuki homepage that there is always the WR at the moment. But I don’t get quite smart about it because there is also any and what about leasing and not wanting to lease it.http://www.suzuki-auto.de/…/swiftversicherung.html Would be nice if one of you could bring light into the dark. After all, you don’t want to get knocked over. Greeting RedNeck
