How many miles had your 22 M3 LR and how much was the trade-in value?
How much did you pay for the 22 M3 LR and the 24 M3H LR? What options did you have? Any FSD?
Did you get any IRA Tax deductions for any of the cars?
What were the sales taxes and DMV fees for each car?
Note: I'm in California, and in my county, the sales taxes are 10.75%
on the full new car price, not just the trade-in cost, so it's a large amount to swallow.
