I was worried too about drilling holes in my nice new car but....
It really is a piece of pi**
The armrest will line up easliy over the cup holders.
Make sure it's sitting nice and flat and true.
Mark the
5 holes to be drilled with a scribe or pencil.
Remove the armrest and carefully drill the holes.
(I used a 2.5mm drill bit)
Replace the armrest in situ.
Use the self tapers supplied with the armrest and secure it to the centre console.
Place the rubber insert over the cut out and hey presto
Easy peasey lemon squeezy
(If I can do it anyone can
)
