@PianoAl, you may be exactly the right person to give me some advice (although I'd welcome the opinions of other readers too)...
I have a 2020 Model 3 SR+ (Dec 2019 delivery) and a 2021 Model Y LR AWD (March 2021 delivery). The 3 was bought just before the pandemic lockdowns, and the Model Y gets used for all the long road trips, so the Model 3 has only ~12,000 miles as it approaches 3 years old.
With the $3,750 off this month for new Model 3s, I am considering selling it and getting a 2023 RWD, which looks like it will cost ~$5k to $6k after selling the SR+ (if KBB is to be believed for private party values). Since the RWD doesn't look like it will be eligible any part of the IRA tax rebate, the December incentive seems a like a good opportunity to get it cheaper.
As I see it the factors are (in order from most important to least important):
2020 SR+:
- Still has ultrasonic sensors
- Worth a little less, so insurance should be a bit lower
- Has passenger lumbar
- A little lighter and a little quicker (I enjoy the feel of the 3 SR+ over the Y)
- I'm going to add a Stealth tow hitch for a bike rack to either car. When the rear rack is installed the rear USS don't work, but the front sensors still have value
2023 RWD:
- Warranty will extend 3 years past the expiration of my 2020's warranty
- Heated steering wheel
- Heat pump for better winter range
- New comfort suspension (I love the M3 handling overall, but it could be better on rough roads)
- LFP battery allows using more of the range in day-to-day use (charge to 100%)
- New cameras / no side repeater glare at night
- Matrix headlights
- Double pane glass
- CCS compatible (I have the adapter for my Y, will need to pay to upgrade the 2020 for CCS compatibility if I keep it)
- Power trunk
- Faster CPU
- New console
I've scheduled a test drive, but I haven't confirmed yet if they have a RWD with the new suspension available to test, so the test drive may not answer some important questions about how the new car will feel.
We definitely don't need a new car. The biggest draw for me is extending the warranty. I doubt we'll spend > $5,000 in repairs between December 2023 and December 2026 (the three years where the old one will be out of warranty but the new one in warranty), so I don't expect the upgrade to make sense purely from a cost perspective, but improved range, comfort, and quality also factor into the return I would be getting on the investment.
