Yep, discount isn't too bad
In summary, no deposit, fixed monthly payment, Road Tax included and no mileage limit. Only cost to me will be insurance and fuel and given that I'll only cover 5-6k miles over the 6 months, no service and no new tyres (fingers crossed)
It's amazing to learn for just how little they offer the vehicles to their employees and I guess it's safe to assume that they still make some decent money from the heavily discounted rates.
