But I have all the options of an LTZ, and I got it for like $12,500 less than an LTZ. But then in October last year, the LTZ was 9k less than what I paid for my LT.

The State Fair is big here in Texas, so there are State Fair deals... but essentially what I found is that this is when dealers are looking to unload their current inventory so they can get the next years models on the lot. So the deals really start to open up. I was seeing deep dealer discounts, along with Chevrolet promotional rebates and other incentives that significantly reduced the price. By end of October, I was seeing 1500 LTZ's for almost 29k... brand new.
