Had it for about 16 months so far. My last car was 9 years old when I sold it. I wish I didn't have to sell it, but it was rusting (due to dodgy repair before I bought it), and it was a bit slow, so it had to go sooner or later. A modern car should still be going strong after 10 years if it's well maintained etc.
I may not keep the car for 10 years. If the gearbox was good, and I liked the car then I would probably keep it a lot longer than 10 years. The problem for me is that older cars are better than newer cars, so in 10 years time I won't want to be buying something new!
