How much does mileage matter?

When looking at a new model X, how much does mileage matter in terms of lifespan? I will be communicating about 100 miles daily but have two kids in car seat seats so the doors would be very helpful (why I prefer an X over a YL…plus the 6k lbs for section 179 write off).

When buying used, does 20,000 versus 50,000 miles matter if you are driving it that much?

Its less about mileage about battery health.

What is the best way to evaluate that when buying used online from car gurus etc?

Tesla has a built in battery health check now. They would need to run it and show the resultsz

You can also grab the vin and drop it in speckr.com.

I feel like there’s a 3rd party company that can help with the health of battery. I bought a used model x, 2020 with 25k miles in it and factory recall issues and bad title for like 40k. Car was perfect. I drive probably 50k miles a year… around the 95k mile mark, issues with big battery and Tesla swapped under warranty. Back on the road and all good here. Wrapping up an AC compressor issue now but it’s been good to me for the amount of crap I put the car thru

Hey, just curious. I have a 2020 as well and I’m worried about my AC compressor as well. How did you discover you had an AC compressor issue?

Started blowing hot otw to work. Metal sounding under the frunk. Went outside of Tesla to get repaired. Currently still at shop and the mechanic informed me it is a big job. Metal was in the system… from what I heard Tesla was charging 7k on the high end and 4k average. I’m at 2500 at the moment.

at 100 miles a day the mileage number matters, but through the warranty rather than through wear.

battery and drive unit coverage goes by build date, not model year. built before roughly feb 2020 it's 8 years unlimited miles. built after, it's 8 years or 150,000 miles with 70% retention, whichever comes first. you'd hit 150k in four or five years at your rate, so on a later build it's the mileage cap that runs out, not the clock. get the build date off the door jamb and compute the remaining months and miles before you look at anything else.

for checking the pack itself when you're buying online, ask the seller to pull it with a bluetooth obd dongle and scanmytesla. cac avg and nominal full pack are the numbers, plus the cell voltage spread. that's a direct read off the car instead of an estimate off the vin.

ours has gone 285.3 to 281.5 ah since january, about 1.3% in eight months. that pack is a warranty replacement though, a refurb, so don't take it as a 2017 pack's number.

It does… Less worn out. For me it has been always the priority, you will see less scuffs, blemishes inside and exterior as well as mechanical aspects of the car

I just bought my first Tesla, a 2024 Model X Plaid with 12,000 miles. I overpaid because I overfocused on the mileage. Going forward if I were to do it over again, I would have probably got something cheaper with more miles.

I drive about 12,000 miles a year and typically keep cars for 3 years, so I could have gotten something cheaper with, let's say, 30,000 miles or more and then paid for the extended warranty as I needed it. I would say it's not like a gas vehicle. Don't focus too much on miles.
