Rust Recall Rip off

So I go in for the "rust frame recall" and find I don't need a new frame. They tell me my truck is the best looking 8 year old truck they have seen. Hmmmmm maybe that's because I know how shitty our roads are and have always winterized my under carriage before each winter. Anywho they tell me my frame needs to be sprayed and then call me and try to hit me up with a $400.00 bill and say the spray I'm getting is like 1200-1500 dollars. I find out it cost Toyota $590.00 so guess what if I pay $400.00 for some repair guess who suddenly is not losing too much money. Bingo! Bullshit!!!!
