I would say that the current M3W's are pretty well sorted from new, although some more issues may have been introduced with the Euro 4. I did not use my 2013 car for any long touring trips for the first 3 years because of reliability concerns but I have done a few 2000 mile plus trips since without any problems. My first continental trip was to Laon when we met at Dover Lowebird. I think good maintenance and seeing what potential problems and solutions need sorting by monitoring TM are the key to reliability. I don't think the M3W will ever be "Toyota" reliable and I wouldn't really want it to be like that. I like that it needs a bit of care and attention, all part of the experience I suppose.
