If service is bad for private individuals, can you imagine what its like for company and fleet cars when the person driving the motor doesnt own it.
I had company cars for 25 years and I'm sure half the time it just sat there for 8 hrs until it was picked up.....Who is going to check!
I marked the oil filter once, to discover when I picked the car up a nice clean filter in place........with my mark still there...it had just been cleaned with a rag!
Cam belts used to let go at 70,000 mile when they should have been changed at 50,000...blah...blah....blah
You get the picture
