Genuine auto or DIY manual

[spannerrash]

Hi all
A bit of a loaded question.

If any of you were in the market for a low ish mileage S8 (89,000), which would you be more likely to entertain?

A genuine well maintained Auto with no gearbox issues at all. Or a DIY manual conversion?

I've been considering for a while about starting to collect the bits needed for a manual conversion but it goes against my natural preference which is to keep things original.

From what I can make out an automatic gearbox rebuild is about 5k and a good manual conversion is about 4k so it's not really worth doing from a financial perspective but which would you rather own?
