Based on my own experience I'd be just a little careful asking instructors. A lot of them have an axe to grind.... like helping a good mate to get shot of his share in some troubled syndicate.
I will never forget the old and highly experienced and knowledgeable instructor who offered me a 1/8 share in a Private CofA plane and saying I could finish my IMC Rating in it. That was half of it; the other half was that it was illegal for IFR in controlled airspace, on several separate counts.
