2011 BMW 328 Advice needed please

Hi

I am thinking on buying a used 2011 BMW 328i that only has 18,000km on it (and also has new tires), and I wanted to know what these cars are like for reliabliity. They are nice cars, but if there are issues that I should be aware of I would like to know as I am older (60) and am hoping that this will be my last car.
Are there any tips you can give as to what to look out for

Thank you

Grant
