howaya, another signet owner here, just joined up myself. they're a great car and unlike the more highly tuned subarus, the engine can take alot of abuse, i've put about 70k miles on mine, most of them at the redline, got the timing belt changed at 120k, think it may have been the first. cv joints are a weak point, i've replaced mine at least 3 times each side, always with second hand ones so maybe new ones would last longer if you could find them.
Rodney Evans Motors in Greystones is probably the Irish expert on these cars, he serviced mine and has helped me out with lots of parts, i can pm you his no. if there's anything you need.
