Reliability - what the heck is...

I think it is best to separate cost from reliabilty, becasue they are essentially different things. Cost has nothing to do with the probability of failure. Expensive parts that fail with equal probability are not less reliable than cheap parts, they just cost more. You may be able to design cheaper parts with equal failure probability, but that doesnt make the car more reliable, it makes it cheaper to maintain.

Does the reliability changes (gets affected) by performing preventive maintenance?
On car A preventive maintenance coststs $$$$.
On car B preventive maintenance costs $.
As one could say the cars spend different time in use, based on maintenance time in the shop.
Do car A and car B show equal reliability?

As I said before,
"to me it comes down to the the amount of time a car operates vs. amount of time car is unable to operate, on average."
and
"I think it is best to separate cost from reliabilty, becasue they are essentially different things."
So what I am saying is that maintenance time should be a factor of reliability but not maintenance cost.

"I don't think that maintenance costs are a part of reliability".
Otherwise the last two posts contradict that very statement made in the beginning. And I would assume that's what actually you wanted to say in the first place; meaning that maintenance cost should not be factored in when discussing reliability.
If one separates (maintenance) costs from reliability, then it comes down to pocket preference, social status preference, etc; it may be fair to say that a Yugo or a Trabant may be as reliable as a Rolls Roys Phantom if both have the same breakdown-free road dependability.

If you don't believe that maintenance is an intricate part when debating reliability, then probably you should change the above statement to :
"I don't think that maintenance costs are a part of reliability".

I think my assertion was fairly clear. And yes you are right, I should have said "a part."

Unfortunately (from a smoke perspective), or fortunately (from a historic perspective), yes...I have driven one 
Oh... forgot to mention: 2 cylinders; definitely it had more power than a present day weed eater that runs on combo fuel... LOL

Lol, sorry I don't want to mess up the topic, but you gotta watch this .
Had no idea there are so many Trabant clips on youtube... hahahaha

Then you should remember on that Trabant the projected live has been set to 100k km.
Needle bearings all over, cars had been sold with a spare engine.
Predominantly the engines have lasted well beyond the projected live.
In the times of gas shortage they were the only on the road running on everything that could ignite.
One of the most reliable 'cars' one could say!
