My local store is great, let me in shop area, I know the techs, two I trust.
One is a Jeeper, who has built a few rigs, the other one of the best trouble shooters on electrical, diesel, transmissions etc
I have an 03 PTGT, was time for a timing belt, WP etc about 1100 job, comment to him He says, oh jeesh your cam seal is leaking and the timing belt is ruined wink
I had the extended warranty which was about to expire at 80 k and I got all the work, timing belt, accesory belts, tensioners, wpater pump cam and crank seals for 100$
Needles to say once in a while I slip them a 12 pack of Sam Adams!
