Anybody who actually helps me out with my car payment is more than welcome to drive my Z.
My wife (who is allowed to dive it occasionally) asked me last summer if it would be OK if she and her girl friend (who annoys the piss out of me, incidentally) could take it on a road trip to her parents' place to "keep the miles off of her Mustang." Said 2005 v6 Mustang has 240k+ miles and I've personally replaced 2 alternators, several wheel bearings, a fuel filter, an entire rear axle, every shock and strut, etc, because she's too cheap to buy a newer vehicle (which she could easily afford) or pay for a mechanic (which she could also afford but what the hell, she has me). The real kicker is she periodically berates me for my monthly car payment.
I very politely invited her to piss up a rope, and she hasn't asked me since.
