VW Passat 54 reg 57k - Cambelt (time belt) change
 

Hello,
I am looking for some advice on changing came belt and long life service. Is VW approved/frenchise garage is better for this job or should i go for any other reputed one? The lowest quote i have received from a vw approved/frenchise garage is £490 for camebelt changing and long life service. What is your opinoin about the price and should i go with vw approved/franchise garage?

Many thanks
