MSRP went up about $500 2018 to 2019 for LT1 Grand Sports. LT2 and LT3 trim levels are more money. Add $5k for LT2 and another $5k for LT3. My guess is that you're looking at discounted/incentivized 2018 LT1s and less discounted 2019 LT3s (or even non discounted LT2s...LT3s seem pretty rare, LT2s seem more common than LT1s).

Edit- I read that wrong. YOu've got to be looking at a 2018 LT3 vs a 2019 LT1 with the 2019 more heavily discounted/incentivized.
