Hello everyone, my first post! great forum I’ve been reading for a while! I’ve been trading 8 years, we have a small forecourt of around 20 and a unit with our mechanic. We currently only offer paint protection as an add on. Today I was looking over a deal for a family member for a car they are buying from listers Bmw, and came across their add ons- gap, dent and scratch protection, alloy and tyre insurance, service packages, etc etc how many of you with a similar set up offer these extras? Which ones work best/worst? Thanks in advance Nick
