Driver's license cost in Munich

I want to get my driver's license and have been looking for driving schools online. I talked with one in particular and they quoted me 4000-4500€, these are supposedly the standard prices in Munich right now. Looking at prices online the cost of the driving lessons appear to be similar across the driving schools, around 80-90€ per normal lesson.

Have prices for the driver's license really gone up this much? I remember my friends in high school paying 3000€. Granted, that was almost a decade ago.
