The 4 cyl Sonata's come with 16" steel with hubcaps from the factory. Did the mechanic actually try one to see if it fit or just said it wouldn't? Unless you can get a set of take offs cheap, it might be cheaper to get aftermarket alloys from somewhere like Tirerack. Check some local junkyards and don't foregt about ebay. My 16" Tiburon alloys were only $100 for all 4 which fit perfectly for my sumer tires and let me use the steelies with caps for winter.
Here ya go, current listing from ebay
set of 4 Tiburon rimsSteel with caps from Tirerack as reference $55 each per rim plus $32 for the 4 caps and the shipping to you.
