They over charge at dealers and don't do the work right. I take mine to an exotic car specialty dealership. Where they work on ferraris. I don't trust dealerships.

 

I am the original owner and this is the first issue I've had. I don't allow test drives and I do bring my own oil(Amsoil)and diff fluid (from Hardtop Guy). This time I used the dealership - I will find out Monday about the diff fluid as I did not have my own to use. I have 68K on my 05 and I have regularly changed the fluids. The service manager had an NSX and we have been friends for years.
