Agreed. Some genuine parts prices are scary!

Some examples from a job I've been doing recently.
Ford Transit 2.2 TDCI service engine (minus all ancillaries) £3900 + vat.
Ford Transit crank sensor - £122 + vat
Ford Transit DPF filter - £1033 + vat (without the EGT sensors/fuel atomiser)

Fiat 500s have a couple of vac breather hoses that split, one of them is about £13 which isn't bad as it's a 'shaped' piece. But the other is a bit of 5-6mm bore straight hose and it's £25!
