I was recently at a Lexus dealership and the salesman proceeded to redline a IS-F for about 20 seconds in park and said he does this weekly or so to help maintain the engine. Is there any advantage or disadvantage to this practice in general? for C5's?

With no load on the engine, the guy's an idiot. Twenty seconds???

I thought that most cars have built in rev limiters to keep from "redlining" the engine while in park or neutral.
The rev limiter is for anytime the engine hits redline, not just in park or neutral.
And the guy was STILL an idiot.
Their may be something to that. I had a rental Dodge Intrepid and it had a different redline while in park and neutral. I wouldn't let me get above 4K I think. When in 1, 2, 3 or D I was able to take it to the full redline.

Excellent. Live and learn. Looks like two different rev limiters, each designed to do the same thing: protect the engine.
With no load on the engine, even at 4000 rpm, the guy's STILL an idiot. He must be a car sales...........oh, wait.

I cant think of much that is worse for an engine than what you described.................that is a lot of reciprocating mass with no load........and the oil pump better not be on break.
I would bet you he doesnt do that to cars he is making payments on and the owner of the dealership has never seen this demonstration.
I would bet the same thing. It scares me to take any car to redline, even rental cars. Something about hearing the engine singing that quickly makes my sweat.
