It all depends on how lucky you are. Have you been lucky with cars?
The first BMW we had was a 5 years old used 160k km E36, saw it in the paper and immediately went to inspect the car in the middle of the night at an apartment in Cheras, took it for a test drive around the car park (max speed 30kph), don't even know how to switch on it's lights, but placed my booking immediately after the test drive.. It cost us RM100k for a used E36 318i(M) back then. Never had problem with the car because the owner just overhauled it. We sold it after 3 years because family growing.
7 years later we decided to get another BMW, it was an E46 but after inspected more than 20 used units in broad day light, I wasn't lucky enough to find a decent condition unit. Hence, end up with a brand new E90 320i with 2 years warranty, zero mileage with super low interest rate. Been 5 years now, no major problem except the many leaks here and there. It's also because low usage, only 83k km now for a 5 years old car.
If you worry about a problematic car, get a Toyota. For my case, I have a Toyota in my stable.. :4:
