1996 Acura Integra special edition

Hi Guys, My question is this I'm thinking about buying a 1996 acura integra special edition from a private sale I did a car fax report on this vechile and it was a MESS the car has been reported stolen multiple times (the car is in Worcester, Ma ) major high crime area anyway I have seen the car its a 5 speed and the interior is in great shape the exterior is a little rough (mostly cosmetic damage) things my current boyfriend can fix the car has 137,728 miles on it. When I test drove this vechile I noticed the ABS light is on and the brakes felt like something was wrong? But I don't know what? My question is this on what percentage do you think it could be something minor to fix (like just a sensor) or something major like the ABS computer module? I need to know where on probability the problem would be? [/Img]
