“Very recently I found that the NHTSA has been investigating problems with many ford vehicles from the 80's, due to stalling problems. I owned a 1984 Mercury Cougar for 2 years and put thousands of dollars into this vehichle with no success. I kept all my receipts knowing that some day the problem would come out. I wish to be part of these complaints against ford and hopes of getting money back due to fords mistake when assembling the vehicles. The Mercury Cougar started stalling almost immediately, but got worse as time went on. …”
