Quirk Kennebec

I had purchased a 2004 *** quad cab. This truck has been in and out of the service department 6 times. they broke both brake lines welded tail pipe together etc. the mileage on the truck doesn't work jerking fume smell detailed the truck and left wax on truck. this is the second truck I have bought from them in the last 7 months and always have problems with vechicles from their. We call or stop in and they do not answer or respond. This company needs to be investigated and all used trucks cars need to be looked at. I bought the truck and they said nothing was wrong with the truck. I have all the repairs slips on the truck. both mangers take off the same day. this happened to the dodge *** we had to that last 3 to 4 months. how did this ever pass inspection.
