I am not in the market at this moment, unless it's a female and there is a four poster involved.
But if someone were interested in say, having a good time with the minimum usage of electrical equipment, I would say something like......
Bentley R-Type, well upholstered, efficient clutch, magnificent undercarriage (regularly cleaned and polished - see photo). When driven hard, will go like the clappers for three minutes and then start smoking. In need of a good wash, rinse and wax hand job.
Polished undercarriage.....
