Tesla Model 3 — real battery degradation after 50k miles?

I'm looking at a 2021 Model 3 SR+ with 48k miles. The dealer says the battery health is around 92% based on their scan, which sounds decent, but I've read mixed things about LFP vs NMC degradation curves.

Long-term Model 3 owners: what does your range actually show now vs when new? And is there anything specific I should check on a 50k-mile example before buying?

A 2021 SR+ is NMC (LFP came to UK SR+ in late 2022). 92% at 48k miles is normal-to-good for NMC. Expect roughly 8-12% loss over the first 5 years, then it flattens. Check the service history for coolant service and tyre wear — Model 3 eats rear tyres.

Thanks — that matches what I've seen. The rear tyres point is real, mine needed replacing at 22k and 44k.
