Tesla still a buy?

$TSLA (+1.37%) In August, I successively bought Tesla shares and took liquidity from Palantir. $PLTR (-0.73%) The price was a little too steep for me. So far, I see good long-term prospects for Tesla: Robot cab (competitive advantages over Uber and co.), robotics and still one of the best e-cars (even if sales in some EU countries are deteriorating).
