FS: 2005 ZHP sedan / AW / Alc / MT / 189k miles / $5,800 / Dallas TX

[QUOTE=csanter;586361]If we were to speculate worst case scenarios, what about frontal impact, breaking the rad requiring the front bumper replacement and then “while your in there” coolant system upgrade?

Only reason I brought it up is that in 16 years of working on these cars, the only times I’ve replaced those cooling pipes is when the engine was severely overheated.

5-10 yrs ago I would have agreed with you, but now that these engines are getting some serious age on them I am seeing the pipes break down and leak. If I have the intake manifold off a M52TU or M54 then I replace them preemptively.

Agreed. I replaced mine at close to 200k and it was worth the peace of mind.

Well if this was $3k higher, then it was about $3k overpriced. It's right around where it should be now, which would explain the price decrease. They probably couldn't sell it at that previous price.

Also, it's not unheard of to replace coolant pipes, even if it was never overheated. Age and plastic don't get along.

Did it sell

Agree about the plastics used back then, compared to new technology.
What sucks is... even the dealer sells these pipes marked made in the C word.
My mechanic seems to think running full synthetic on the older cars may be overkill,
especially here in Texas. He may be on to something?
I would pull the trigger on this one in a minute, but starting to believe I'de be better off finding
one (ZHP or M) to truly "collect", instead of DDing.
