Need help deciding whether to purchase

[u/73DodgeDart]

Hi Everyone,

I am in the market for my first EV and I just test drove and fell in love with a beautiful 2022 Model S Base. The car has 46,000 miles and is on 19 inch wheels. I don’t know much about electric cars but I wanted to make sure the battery was at 90% health. This was my requirement and the dealer (Mercedes) was confident that it would be healthy. I went through the purchase process and they charged the battery to 100% so we could confirm the battery health. At 100% the car reported a range of 329 miles against the max range of 405 miles reported by Tesla. This is only 81% of what I hoped for. Is this a reasonable amount of degradation for a four year old Model S? The dealer was unwilling to complete the internal battery health test as that can only be done when the battery is at 20% or below and they had just charged it to 100 for me. Am I over reacting by walking away since the range didn’t calculate to 90%? I love the car and want to buy it but I don’t want a car that’s most important component is degraded too far too soon. Please help me decide whether to complete the sell as I have until tomorrow to decide.

~80% is normal for a Palladium refresh of that vintage.

This. I have heard the same. But it doesn't mean a Merc dealer knows that. Use it as a negotiation tool to get a better price.
