More interested in information than selling cars

Surreal experience: I was looking for a new car at Suzuki Silver Lakes, and spent a pleasant few minutes with the sales lady. For a test drive she scanned my driver's license, and then wanted a cellphone number and email address. I declined, because I do not want to be on yet more mailing lists and be targeted by endless adverts, or add more information for the delectation of identity *******. The lady assured me that that would not happen, but then they always do promise that, and it almost never happens that way. I pointed out that I could always make a 'mistake' when supplying my contact details, but would rather prefer to be open and honest about it, but then I expect them to be too. So she went to fetch a more senior person, who bluntly refused me a test drive without my phone number and email address. One wonders whether that means that people without such things are not allowed to buy cars? Anyway, I had to leave - pity, for the cars looked nice. Clearly dealing in personal contact information is more important to them than selling cars, for that information does not increase their security one bit when I test-drive a car. Which means they were lying about the reason they wanted it. The sales lady probably believed what she told me, but clearly her superior knew differently.
