2003 Saab 9-5 check vin please

I am considering buying a saab and was wondering if someone could please check the VIN for me. It has 150k miles and has the 2.3 turbo and manual tranny. Does anyone have any recommendations for me to check, Good car Bad car? Is this one of the engines with the sludge problems? The vin is YS3EB49E533039877 Any info would be great thanks. I know nothing about saab. They do have maintenance records.
