I recently had to replace my ac compressor. Indy shop quoted me 1030 for a BEHR replacement. I later found the same unit for sale on ebay for about $460. Shop agreed to use the compressor if I brought the item in.

I bought this same unit last week and had it installed with no problems. Good luck.

I have an 08 bmw x5 4.8
