Well, I am only 17 but I suppose this could work with parents.
My mom loves my (well, technically theirs) Discovery. Occasionally she'll steal it from me. She knows its not the most reliable car but neither is hers.
My dad is a bit skeptical about the Disco. In his youth he had a 1963 Series IIa that was his pride and joy but it was unreliable and he needed a more efficient, roadworthy car. His SIIa was unreliable and he knows that the Disco isn't that great reliability wise either, but at least you could work on the SIIa a lot easier than a DII. Although he notices Land Rovers have turned into plush luxury SUVs, straying from their heritage, he will admit they do have capability unlike many modern SUVs and he enjoys the ride height and visibility.
We'll see though...
