4000 Downpayment + destination
654 * 36 = 23544
-1875 Federal Tax Credit
-5000 from selling RS
Cost = 20669 over 3 years

RS Sale = 31000 - 12,500
18,500 Return (possibly)
5000 used to start lease, invest remaining 13,500
13,500 at 4% over 3 years =  15,185



34 Payments left on Focus
450 * 36 = 16200
Maintenance ~ 2000$ (Will probably need new tires by then).

RS worth in 3 years with 26,000 miles on it...
Maybe 25,000?
25000 - 18200 = 6800

If I pay off the RS it will cost us 18200$ over the next 3 years and we'll be left with an asset worth 25,000
If I sell it that day, I will have had a net cost of ownership over the period that is positive 7000. It also has a full warranty for 6 years which limits risk.
Cost = 18,2000 Estimated
Asset = 24,0000
Net Result = 5000 to 7000$ (Depending on how much it sells for)


If I get the Model 3 it will cost us 20669$ over the next 3 years, and we'll be left with an Asset worth 15000$ (The Cash from the RS)
Cost = 20669
Asset = 15000
Likely Gas Savings from 30,000 miles at 30 MPG and 3.75$ per gallon = 3000$
Net result = Loss of 2,500

We will be taking a hit of 7,000 dollars by getting the model 3. This comes down to 194$ a month

The question is whether or not having the performance model 3 is worth an extra 194$ a month compared to driving the RS. This fact stands regardless of who is paying for it. I don't like to waste my money or other people's money. Even if squeeze paid for the whole thing I'd still say no if I didn't think it was worth it.

Pros:
Faster than the RS
Better Tech
Comfier
Better for Passengers
Cherrie can drive it
Safer
Better for the enviroment
I have to explain to 98% of people what a Focus RS is and everyone will know what a tesla is

Neutral:
Not necessarily as thrilling as RS, but more thrilling than the civic, and we would be driving it every day so it would even out (Besides most of the time I drive the RS in traffic anyway which kills the fun).
Electric, lowers flexibility but also we have a second gas car

Negatives:
Not as flashy as the RS for those who know what it is
More common
Automatic, in a time when Manuals are becoming increasingly rare/valuable
