I still haven't learned my lesson with cheap parts.

If you don't plan on keeping your car for another 5 years or so, then the some cheap parts are maybe OK.

I have a 1991 300CE. I changed motor mounts at 135m, 12/2005. These were ORIGINAL to the car! Fourteen years of service and 135,000 miles! I used non OEM part and recently replaced them again. Cheap parts = only 40,000 miles and 6 years of service.

Changed the ORIGINAL fan bracket at 144,000 4/2007. Sitting here doing it again at 180,000 just 5 years later. The original bracket lasted 16 years!

Back then, dealer did not have rebuilt fan brackets but now they do. For my car it was about $155 with $15 core charge.
