tfw your friend gets a brand new car (as in first model year brand new, as well as "lose 25% off the lot" brand new) for a bunch of marketing reasons when they could have had a better car for a lot less money.
it's like when people tell me they bought a computer at Best Buy followed immediately with "I thought about calling you first, but"
I guess still have trouble letting go of having my advice valued as the engineer friend, even though it's often annoying to be the engineer friend.
