SInce it's a 2018 build, you'll get 2018 hardware in the car that 2020's don't come with. They were mentioned above:
- Homelink module installed (and since it's an LR, will have Homelink software included)
- Dimming side mirrors
- Leather steering wheel
- All charging adapters
The VIN is late enough (13xxxx) that you will NOT have the items some of the early models had like the harder seats, the older glass roof coating, stiffer suspension, etc.
What you do need to keep in mind and check carefully is that it also sounds like the software and option package will be packaged like a 2020:
- Pay-per-use supercharging (if this car had been sold in 2018, it could have had lifetime free supercharging)
- Pay monthly for premium connectivity after the 1st year, which includes real-time traffic, TuneIn, etc. (If sold in 2018, this would have been free for lifetime).
- Standard AP, or you might add FSD at the $8K price. (If sold in 2018, would have had no AP, EAP for $4K, or FSD for $7K).
One further item to keep in mind that cannot be changed is that the battery has 2 years of time on it, even though it has almost no cycles on it. Normally the battery warranty is 8 years or 120,000 miles, but at your 8-year ownership point, the battery will be 10 years old. I do not know exactly how the additional 2 years will affect the battery retention that far out, but it's something to keep in mind. If the car was indeed a showroom car, then it was kept in a climate-controlled area and temperature aging effects on the battery should be minimal.
Assuming the car is sold as "New" in the legal sense and you have full warranty that applies from the date of purchase, then I think it's a great deal.
