Ironically the least solid, least reliable car I have ever owned was a Toyota. After 8 years it was very poor. Other, older, cars I have enjoyed more reliability with have included a Honda, a Kia, a Fiat and a Lada.
In general they were all beaters that barely ran, but they ran. One corolla went for 2 or 3 years without an oil change and had 2 cylinders with low compression. Friend never got it fixed, but the car was still running (although with very low power). I actually think the general reliability of these cars leads to them being in worse shape. They're running so why bother to fix it. The owners also had a drive it until it dies approach, just generally took a long time to die.
