When the vehicle runs out of fuel, you put more fuel in it, but when the engine seizes, we will put you on ebay as parts, and bits of you will live on in other peoples cars, where your parts will provide useful service.
When a car gets broken up, what happens to the smell, the smell of the leather, of the engine, of the interior, no car I have ever owned has ever smelt the same as any other car, it is the first thing I do when I get in a car, not a new car, as it has no history, it has not driven anyway, new cars all smell the same, beats me why people buy new, but go into a 10 year old car that as had a life, and been looked after, and the smell, the smell describes everything that car went through, all its experiences, all its moments of hurtling down the M1 at 150mph, or of toodling in traffic at 10mph, every accident, every bit of polish, its all there in the smell,
So when every part, every tyre, every panel has been integrated into another car, the smell, what happens to the smell, it just wafts of into the air, and every now and then, you might be on a beach, you might be on holiday, you might be in bed, but every now and then you will catch a smell, and say, that was my car
