What should we notice while comparing cars

Hi Dan, thanks bucket loads for your article! Very well written and easy to follow!

Wondering if you could help me out? I have a Ford fiesta ghia 2005, about 100,000 km on the clock.

A few months back I noticed my cars radiator fan would keep running once I reached my destination after a long drive (it never really did this before).

After a couple of weeks of this my radiator burst after about 5 minutes driving. The temperature warning light came off and I was able to turn the car off straight away, we let it cool and the mechanic took it away and replaced the radiator.

About a month after that we had a hose burst towards the back of the motor (not sure where exactly). This time the temperature warning light came on and then turned off, so I kept driving (not knowing the pipe burst). I drove about 4km before the light came on solidly, then I stopped and there was still quite a bit of coolant coming out on to the ground. Once again, we let it cool and the mechanic took it away and replaced the pipe.
