I went though the same exact thoughts as you.. If money is no object and you can comfortably fit in the seats, go for it - other than that see below for my thoughts. I sold my daily driver since I don't drive much any more (got a great price). "Daily" driving this car lead me to a few conclusions:
1) I barely can go WOT as it is in my 2SS around here...partially because of the long gearing in the manual. You didn't mention which transmission you have, but from what I read the gearing is even taller in the ZL1 manual.
2) I prefer naturally aspirated with this much HP.
3) Interest rates are much higher now, I got GM special financing at 3.49%. My payment would more than double, APR would double around 6-7%, and I would lose the 7k in taxes since CA requires tax on the full car amount (no trade in credit).
4) I actually find myself looking for a lower power manual daily that I can actually ring out. Don't get me wrong, I love this car, the power, and the v8, but my whole life I've had relatively low hp (200-300hp) manual Japanese cars. I sometimes miss the shorter gearing.
5) I sat in a brand new ZL1 and didn't feel like I would be comfortable in the Recaros. Sure some folks say you break them in but to be honest I felt like i was sitting on top of the bolsters.
6) The handling upgrades from the ZL1 I probably will never use without going to the track. The car handles great as it is. I try to convince myself to get the GM performance suspension upgrade (non-mag ride), but everytime I drive the car in the canyons I see no need.
7) The luxury bits in the 2SS package make the car feel special, especially at night. I definitely utilize the 2SS more than I would the 1LE.

All this to say - the ZL1 is a great deal, there is no better car for the price. I mean I just read a Car and driver in which they compared the new M2 to a SS 1LE. It's basically neck and neck with that car, and the SS 1LE came out in 2017 and is more than half the price. That tells you what a bargain these cars are.
