We are also lucky enough to have good mechanics very close by to fix and modify our cars. It must be difficult to find a reliable M3 mechanic in some parts of the world.
The government takes about 30% of my paycheck I think. Then at the end of the year I get like 10% back on my tax return. They also take ~ 9% sales tax. It's really not that bad of a deal.
How much does a fully loaded M3 cost in Germany and what is the tax system like?
