In recent years, booking a service has become an unpleasant experience. The days when you could call the dealership service department, discuss your requirements and book a service have long past. It's now a call centre with non technical people operating from a script. The last 3 occasions I had to use them resulted in many errors such as wrong date, wrong location, messages not passed on etc. I called the dealership this afternoon for costs and was transferred to the call centre who told me £320 for Intermediate and £580 for Full service including spark plug change. When I last enquired at the dealership they deduct £170 if you fit your own plugs (at a diy cost of £45 for OEM plugs plus 15 minutes). The call centre young lady told me the cost is the same whether I have plugs replaced or not. I asked to be transferd back to the Dealership (whom I originally called) when the line went dead! I didn't get the chance to discuss the £100 previously quoted price reduction for OEM oil I always provide (£54.98 for 5 litres 0w20 from Snows Toyota, Exeter) with service cost always historically reduced. I would be interested to hear others experience and whether it has proved benefitial to have servicing done other than by Lexus.
