I decided to get a C1 because I liked another 2015 C1 1.0 that belongs to a family member but this one is a 1.2, I don't know much about cars so just thought this was a slightly larger engine in it so I put down £500 deposit on the car (£4k cost in total - insurance money is paying for it) because it looked nice and seemed to drive nice when I took it on a test drive, the garage offer a 6 month warranty with used cars (not a main dealer). I have been reading that these engines are nothing but problems for people because of a "wet timing belt" system? Did I make a mistake buying this car? I don't think I can back out now and in any case if I did then I will lose the £500 that I can little afford. I can only afford this car because of the insurance money. The garage I am buying it from seem decent and reputable and have been around longer than I have been alive (

).
I had no idea that there could potentially be an issue with the timing belt. The car has done 70,052 miles and has had 5 services and the garage are doing another service on it for me now and a pre-delivery inspection. As I say, I know nothing about cars and I'm really worried now. I just want a car that will last me at least 5 years?
Here is the vin, in case you can provide me with some more information about it? VF7**************[VIN obfuscated, can be read by forum staff]
Should I be worried about this car?
Thanks for any advice or help you can give me.
