My car is definitely on the way out. I decided that the spots of oil left on the road suspiciously near where I park it are somewhat embarassing and antisocial so took the car to the garage. They said it was the gear box, but since a number of other major things need doing to it they though I should 'call it a day'. Wretched thing, it's only 7 years old and has been serviced in line with manufacturer's guidelines. Gah. Admittedly it has done 120000 miles, but even that isn't unreasonable one wouldn't have hoped.
