Machine wash or hand wash only?

[danny wilde]

I kept my first Aston Martin from new for almost 16 years and only did hand wash, never machine wash with brushes.

But, looking at my daily driver, that gets machine washed with brushes only, I must honestely say that paint scratches on both cars are equal. So, I somehow think that It is not worth the effort to go for hand wash only.

What do you think? Do you use machine car wash with brushes for you beloved Aston?

Thank you all for your input. Car wash seems to be a science in itself.
