Hey I've had my TE a year and kept it regularly serviced, but ive got a few questions, its done roughly 347,000...Should I be getting more done than just a regular service from Good year?

Unless it really needs it, you shouldn't need to get them to do much more than usual... Just get them to keep an eye on oil leaks, CV boots, radiator hoses and other perishables that may be suffering after 350,000km
