They over filled the transmission fluid so you could take it for a test run but the transmission was leaking like a sieve and so was oil and break leaked. . Asked the dealer if he would fix those leaked. He laughed and said no. My mechanic said it would be a big mistake to buy it

I love this truck. It has everything I need for work and home. The back seats have enough room, especially if you have little ones that have to be in car seats.
