I don't really trust dealers to work on my car.
Last dealership I went to I brought my stock 1997 240sx to get the waterpump changed (Should have done myself). Two NISSAN techs came outside and complimented my on my R33 skyline. When I told them it was a stock 240sx one asked me if I knew I had a skyline front conversion on it
Got my car back 2 hours later and go a mile down the road, car overheats. I look under the hood and they had forgotten to put ANY coolant back in the radiator
Returned to the dealership and they filled it back up. The next day I was driving and my water pump belt grenaded
I've swapped engines, transmissions, done turbo builds and done a frame off resto with no problems. Crappy Nissan dealership can't even replace a waterpump.
