Troubleshooters

Took my Jeep to Troubleshooters for overheating when another mechanic seemed to be having problems fixing it. They determined it was a leaking head gasket. Gave me a price ($ 1200) that later turned out to be the labor cost only — didn’t include cost of work/​parts at machine shop. Got price for that (another $ 1700), and agreed because it needed to get done. Then *another* part was required, for another ~$ 100. Asked a friend who knows about these things, said it wasn’t unreasonable.
My main complaint (after sticker shock) was the time it took — five weeks. The machine shop was closed one week (the week of Thanksgiving), but Troubleshooters had the Jeep two weeks at that point. I get that these things take time, etc., but five weeks is too much in my opinion.
No complaints about the quality at this point.
