As i said before most people save money over the three years.
I have nothing to gain by misleading you, i've not sold it to you.
As for those that have paid £ 99 for a service at 30 k
Bet your on time distance, and are doing less or possibly equall to 10 k miles per year.
The guy asking the question will be at 30k miles after two years, it makes a massive differance.
But at the end of the day, you have to be comfortable with the payment, personally i would prefere to pay 50 per month than have one big bill all at once say £ 400, and i bet sure as eggs is eggs your service light will come on as your tax is due, so £ 400 for service and £ 400 quid for tax, i bet you wish you were paying 50 per month then.
