I think that's BS. I don't believe it. Every car I have negotiated a price on was done prior to them running my credit. Dealers don't run background checks on people. Do they have some secret database that they all contribute info about their bad purchasers - no. Anyone here ever use the lemon law and have a story about their subsequent purchases?LoanWizard said:Once you use the lemon law you can kiss off ever being approved for any kind of manufacture financing and dealers will never sell you a vehicle below MSRP. In other words you better make sure that was your last resort because you will be unoffically blackballed.
