tested
I have been weighed in the balance and not found wanting. Be very afraid.
(In other words: I somehow managed to pass my driving test. This is a Good Thing because my theory test would have expired in three days, and a Bad Thing because I am clearly far from being an expert driver. On the other hand, I do know I'm not an expert driver, which apparently distinguishes me from the majority of people who have just passed their test.)
I have absolutely no idea how one goes about buying a car without spending far too long on it or ending up with something deeply suboptimal. I suspect the answer is that most people spend far too long on it or end up with something deeply suboptimal.
