I know this is a great place but I keep forgetting it is US based. Is there an equivalent UK place as I get confused when reading certain things and people talk about parts and gas (petrol here in UK). I am also not used to waiting for this activation ring when you post.
You could try the Toyota Owners Club | Prius Club, although the information for all generations of Prius is all lumped together, which I don't particularly like. It is also less active, but there are enough people who respond to questions, so that is okay.
I'm in Manchester, UK and been here for years. A Prius is a Prius and the info on here is top class. I don't see a real problem. If you want to know something that's specifically UK based then just mention it and the UK folk will chip in. You won't find a better forum than this for the gen 2 Prius.
Yes the Americans use tire; wrench, trunk etc as we know. It's weird that different countries have different spellings and words for the same parts.
And really they are only a handful of countries that drive on the left. I think Australia is another but not many.
