t180 keep or sell ?

[Slippy]

I have a toyota avensis t180 2007. Has 130k miles and a full service history. Owned it since January and in the last month 2 fuel injector seals have blown, they were the copper style that are apparently weak. Going to replace all of them this weekend and hopefully all is well. 

Should I sell the car once this is done, or is this just a one off ?

Are the t180 cars reliable in general ?

Will the two blown washers cause any damage to the car ?

No don't sell because of that because most diesels do that it's nothing if that's what it is easy job I would put the injectors back in the same order they come out and also make sure that the injector seats are very clean best use seat cutter just to clean good luck
