I think it matters quite a bit, but for testing rather than buying. If I know that I want a Tesla I can drive for an extra 40 minutes to buy it. If I am deciding between, say, a Volvo, BMW or Toyota I might test drive a Tesla if it is close, but not if I have to drive 40 min each way. This may not be completely rational (test drives take longer than we budget for), but it still affects such decisions.
