Specifications and data which Sera owners may find useful:

I'll add information to this as I go along, part numbers and so on. The Toyota Sera Register at http://www.toyotasera.co.uk/ is extremely good for supply of parts and information, especially if you don't have a helpful main dealer to hand. Most motor factors won't be able to help you with some parts, for example the Paseo air cleaner element is the same (but a tight fit in my experience, so perhaps not identical), the oil filter is common to many Toyotas, but the timing belt is different to that on the Paseo apparently.

There is an excellent technical description page available at http://www.omicron.uk.com/sera/aboutsera.html showing colours and standard information about the car.

Nick Saalfeld has an excellent online parts guide - it isn't 100% complete, but it's got everything you're likely to need or, more importantly, be able to get. http://www.saalfeld.co.uk/parts1.htm

Information gathered from as many sources as possible; Toyota UK, Japanese Sera webpages including the Sera Club, Sera Yahoo group, toyotasera.co.uk webpage etc. I haven't written any of it, just stuck it all on one page or noted part numbers when buying stuff. Errors may exist on this page at present, I'm still verifying bulb types for example.
