Can't help you with the Central IL., part. But have a "sleeper" dealer here in VA with allocation and not many buyers in the market. You could obviously do a museum delivery as I have with Les Stanford in years past or simply a courtesy delivery locally.... My 2015 was 7 weeks from order to production (6/27 to 8/13) 3LT/Z51/Coupe. Awaiting shipment after any QC holds. If interested PM me for contact info.How would I find out the dealers in my area (Central Illinois) that have allocations for the 2015.
