That's an attribution problem rather than a retargeting one. A long period of research prior to car purchasing is well documented[1] - the problem you have here is the conversion hasn't been connected to the retargeting. If they had an efficient way of saying "Excellent - after 10 weeks of research dx034 has actually bought the Audi" they could switch you off. Until that's noted, or you drop out of the 'this is the longest period people are likely to shop for' bucket, you're going to see the ads.
