Just posted this under General Maintenance but that forum looks a bit quiet and this is really in relation to the GS300 :

I've noticed some on ebay, and some on workshopmanuals.co.uk (which report to be the Mitchells MODS system). Does anybody know if any of these are any good for maintenance/repair work or are they just a glorified owners manual?

They are ok, have wiring diagrams and show parts etc. but don't really have step by step instructions on how to do things.

Lots on ebay etc. although they are just copies of the software and therefore if you don't have a license it would be illegal to use it.

You may want to look at http://www.alldatadiy.com instead.

Thanks Colin, I'll take a look. Just curious at this stage really. I think the car may well be too complex to consider doing any real work on it if the time comes (touch wood it won't)
