I am on my third lease contract. In my experience they allow for fair wear and tear, but check the scheme follows the bvrla guidelines. I haven’t had any issues at the end of contract, but my first car was stolen before the contract ended (a few hassles in that, but no more than a private car), and the second I part exchanged for my current car, with the garage settling the outstanding finance, and they didn’t even look at the car.
I normally just chuck a large groundsheet in the boot before putting a bike in, and haven’t managed to damage a car yet.
I am very careful of my cars anyway, so don’t really have an issue with their lease t&cs for damage. My pay scheme for work sort of forces my to privatley lease a car for work use. We also own outright my wife’s car, but thinking of switching that to a leased car in the future.
