A relative of mine wants to borrow my car for several (as yet unspecified) days. She would want me to drive to her flat first thing in the morning, and leave the car there and walk to work from hers (closer than mine, but still a good 20-25 minute walk). I would then have to do the walk again in the evening to pick the car up and go home. She also wants it overnight in the Summer to take her DD on a trip somewhere in the holidays. She thinks I will just say yes because when I was learning to drive, she helped me out with private lessons.
The reasons I do not want to lend her the car are firstly the inconvienience of the time added onto my day. It's not only the additional 40-50 minutes of walking a day, it's that traffic is horrendous from her house to mine during rush hour and could add another half hour onto the drive. Insignificant to some perhaps, but not to me. Secondly, while she would be insured correctly on my car, I have found out that she drove without insurance or a valid licence for many years with her own car, and it makes me skittish about her driving mine if she was willing to be what I think is reckless. Maybe I'm being pedantic, but I wouldn't have taken lessons from her if I knew she was willing to do that (although she was insured on my car and used it at the time even when I wasn't having lessons). Thirdly, she has questionable personal hygiene at times and I don't want my car smelling horrible when I have to get back in it. She would probably smoke in there, as well as have her dog in the car (I'm a dog owner/lover, but he wees everywhere, and I don't want to smell that either!). I also suspect that she would not put petrol in the car, so this would end up costing me a lot.
So am I being unreasonable to say no to her using the car? I know she's going to be very annoyed with me if I say no, but all things considered, it's just going to be a massive headache for me. The overnight is a definite no btw. She doesn't work so can't afford her own car.
