Hi Drew
I leased an AT4 on 6/30 - post on page 31 has the lease details. I live in S.Cal and not many dealers would offer much off an AT4 other than the factory rebates. I talked to at least 15 dealers who had trucks I was interested in. I had one dealer more aggressive than the truck I bought - but found out after they gave me the pricing the truck has 450 miles on it and they had it on the lot for 5 months - $70k MSRP. They offered similar discount to what I got, plus they threw in $2k in dealer cash - so about $10k disocunt.
The Carbon Pro Edition I got was exactly what I wanted - It was in Phx (350 miles from me) - dealer is shipping it to me at no cost to me. All the paperwork was done in the mail. Great to work with.
MSRP $66,635
Dealer discount $4,362
Rebates $3,650 ($3,400 on GM lease and $250 for GM Loyalty - 2015 Z/28 bought new from GM)
Total Discount $8,012
Net cost $58,623 + tax and License
So not as good as some deals posted here, but I got exactly what I wanted and got a good discount. Big volume dealers can offer the biggest discounts as they get GM cash for sale volume, they can apply to future sales. So bigger dealers with lots of inventory will provide the best deals.
I think the incentive for the AT4 went down in July for a purchase from $3,500 to $2,500 (leases are $100 less). There are other rebates, for example I got the $250 loyalty rebate for the purchase of a new 2015 Z/28 a few years back. There is an educator rebate, a first responders rebate, a military rebate and of course best of all is the GM friends and family rate. Working with a dealer who knows everthing that is available is key to getting the most off on your truck.
You will encounter some that say I will give you rebate and discount the truck $1k off - you likely will not make a deal with those dealers - Tell them what you want and stick to it and go to multiple dealers - you will find some will not be interested in your deal, but likely someone is for whatever reason - maybe they need one more sale to hit the next level of incentive with GM - end of the month is best time to get biggest disocunt.
However now inventory of 19's will be all delivered by next week - so strike quick, as inventory drops it might be harder to find what you want at the price you want!
I had a dealer call me this week who said no way to my offer two weeks ago saying we can do the deal - I said no longer interested, they offered a better deal - I then told them I already bought a truck, but thanks for the call. So dial for $$$$$$$
Good luck finding what you are looking for!
