The oil and filters would be under £150
Whenever I've bought parts from a motor factor it says on the invoice , all parts supplied meet or exceed OEM specification
Charging £1500 to service a diesel is taking the ****
I had a fiat van , fiat wanted £450 for the second service so I took it to a local garage, £200 , it needed warranty work a few months after and they didn't even ask for the history
I doubt the Maserati arm would be so accommodating , yes your service history complies but the GPS shows you driving past a race track , sorry
The way the ghibli depreciates there's no way I'd be worried about a main dealer history , will it make much difference to the value on the car at PX time , certainly not £1200-1500 a service worth I wouldn't have thought.
All the diesels I've owned have been in and out in 2 hours so where they're getting £1500 from
