I just got my car from Mcleods 4 months ago its already having severe problems and been in there shop for almost 2 weeks. My car payments are high and they told me before buying the car nothing was wrong at all with the car they even tried showing us the Carfax. Now its not determined fully what the main issue is but other then that they were pretty persuasive in getting us to buy the car.
