The better answer is that nobody should buy VW either. Their business has zero potential upside and a huge downside risk in the transition to EVs; along with the inevitable rise of China's domestic automakers, which will eat a very large amount of market and sales away from the old giants. VW's position is its weakness, it has everything to lose and nothing to gain from the peak they've reached.
Which also isn't the same as saying that Tesla should be bought at its present absurd valuation.
