zahavasdad,
So is it Daas Torah if someone asks if they should buy a Honda, Toyota or a Chevy (People do ask such things incredibly) and you get an answer
Do you really think that there are rebbes out there who order their adherents to buy Toyota Siennas, threatening cherem to anyone seen driving a Honda Odyssey or G-d forbid a Kia Sedona?
One would certainly ask for a friend’s advice before making a big purchase if he thought the friend had some insight; why is it such a horrible thing to ask for your rav’s advice (or bracha), if he is your mentor and friend?
