Called, made appointment date, was given a quote of $ 336 for work to be done. Arrived @ 7:30, service adviser came out to truck @ 7:50 . Entered office and first thing adviser said quote was for car, truck labor would be $40 more, then would give me 10% off of $376. I said OK. Had to leave truck, guaranteed it would be ready by afternoon. Received cal from adviser stating now bill would be $900 and something, explanation was $169 for "tune Up" $ 25 for service essentials and for 2 coil packs I might or might not need @ $108 apiece . Told him I only wanted the plugs changed , there are 16 on this model truck, asked did they break coil pack, adviser said no but it could happen and I would be responsible for them .There are 8 coil packs on this truck. I could be liable for 8 @ $108 each, worst case scenario, non at best, if "they" break them. Told adviser to put truck outside & I would come & get it, He "said" it would be $149 for checking out the truck. After some discussion I could just pick truck up. A day wasted miles spent to & from. To say the least, not at all satisfied with "results" or the lack of.
