Thinking about Buying my first RM? Where to start?

I’m thinking about buying my first RM.
But where should I start?
I’m based in Germany and living about 2-3h away from the next boutique in Munich.
I would really love to get an RM 67-01 in Titanium. But I would also settle for a RM 10( I’ve heard they are producing them again).
Something in the low 100.000€ range.
I have a friend who’s buying a lot of watches. He sometimes gets to buy some older RM 10 for about 75-85k which sounds amazing to me. But the market for RM watches is really slow in Germany.
Would it benefit me if I would buy an RM off the grey market or will the think that I’m just buying one to flip it?

Should I visit the boutique frequently.
I’m 2-3 times a year in Munich rn. Should I always book an appointment?

Have some of you had some experiences with RM Munich?
