I've driven manual shift cars all of my driving life, more than 30 years so far. I'm 52. I'm thinking about exchanging my mid-sized manual for two cars, a runabout for everyday use, perhaps a Toyota Yaris 1.33 and a civilised 'classic' for pleasure. I like the Mercedes W107 3-litre SL that ran for many years up until around 1989. There seem to be plenty around so, with care, it should be possible to find a good one at sensible money. However, as far as I can see, all the 1980's SLs are automatics. In your experience is switching regularly between a manual and an automatic shift car a risky business that could result in the terminally confused becoming a danger to themselves and other road-users?
