what is the minimum or maximum repair cost have you experienced

[Perfectlap]

$5,500. But this was a combination of repairs that occurred right on top of each other, no time to even take the car home. I believe I had a failed starter, alternator, the catalytic converters had it (I went with a whole new exhaust), bent wheel and damaged tire (had to replace all four due to discontinuation of tire) the AOS and MAF were replaced, and the ignition switch was asking for replacment. It was as if the car was engineered to have all these things go in one big wave. This wasn't too long after I'd spent $3,000 on the clutch/ims/rms. And last year I had about $6,000 in repairs for the suspension overhaul and brake/rotors. The interesting thing in all of these big repairs is that labor was never more than 1/3 of the bill. My mechanic as very reasonable $85 rate per hour given the shop's experience with Porsche. It's the parts that make keeping these cars expensive.

cheapest was ~$300 for a failed throttle body.
