The first and LAST time I buy from Columbia Used Auto Parts. I purchased a "low " milage engine and uopn delivery my tech noticed lots of rust in the cylinders. It took 1 week to get them to exchange it and when the 2nd one got here we noticed lots of sluge in the oil. When I called the owner they told me my money is unrefundable and that they sell these engines everyday to people in this condition. BAD BUSINESS!!!!!
