Will she make it?

With a well prepared car you shouldn't really have any issues, although it's wise to take a few tools and spares as a precaution - especially RHD specific bits that WILL be a headache to obtain quickly in Europe (e.g. clutch cable)

I'd strongly suggest fixing any known issues now though, rather than ignore them and risk them becoming a show stopping problem hundreds of miles from home. Hesitation/misfire would certainly want sorting out, as that would put somewhat of a downer on your trip if it is a coil starting to break down and it failed completely.

18 months back I did a 3000 mile 10 day holiday around Europe in my 205 and it didn't miss a beat the whole trip, including several days in the Swiss/Austrian/Italian Alps on the wonderful mountain passes there.

Economy will vary massively depending on the roads and driving style, but broadly speaking, you should see good economy on a long motorway cruise and rather worse economy on mountain roads if you take the scenic route (which I'd highly recommend btw). I think the best I managed from a tank on my 205 1.9 GTi was 42mpg - not bad for a 30 year old design engine/injection system!

Do check the requirements for other countries before leaving, as some (like Austria and Switzerland) you need a Vignette (sp?) - like road tax - and others have things that you need to keep in the car like hi-viz and spare bulbs. If you're planning on heading down through France, check the costs of the motorways as much of the network is tolled and it does quickly add up cost-wise.

Quality info, thanks mate, yup I've got a few bits bought already, some bits are already on there way or only have a few thousand left in them, again working at EPC I get some nice prices lol

Is there a workshop manual for the 306? Is the Haynes one any good?

Yup Vignette and a few other bits I'm aware of, especially with regards on legal requirements, that said... What's the quickest way through France?!
