Decided against a caddy STS, thanks to some insight offered here. Test drove an Olds 2002 Bravada with the 4.2 engine. Really a nice vehicle. Any thoughs, negative or positive on this vehicle? It's got 72k miles on it but is in very good shape.

Thanks.

The Bravada has the 4.3 V6. The only real issue with the engines are the intake gaskets. Other than that they run for a long, long time.

The police in the USVI use chevy trailblazers (with 4200s of course) as their police vehicles. They seem to hold up well.

USVI severe service puts more or less any severe service we have here in the states to shame.

I've got one in my 2005 trailblazer and love it. 2002 was the first production year for the 4.2L I6 and a range of 2002 VIN #'s had issues with loose cylinder sleeves. Problems were rare though. Here's a cool write-up on the vortec 4.2L: http://media.gm.com/division/powertrain/news/4200_Tech.pdf

I personally dont care for the full time AWD systems used on the GMT-360 chassis (hi end TB's bravada's, envoy, rainier, etc..). It's expensive, complicated and not as commonly used as the part time 4x4 system for this chassis. The 4L60E trannys are used throughout. Parts, service and knowledge are plentiful for them. Sad thing about the vortec 4.2L I6 is, it looks as if the last year for it will be ~2008. GM is ousting the GMT-360 (med sized, full framed, truck based PT 4x4/AWD SUV) This is the only vehicle this engine is used in. It wont fit in much else. [Frown]

If they would just use it as the base engine in the 1500 trucks and the top of the line engine for the Colorado it would make alot of people happy including myself

From what I've read, the smartrack system used in the Bravada uses rear wheel drive until slippage occurs. Then the AWD system takes over. From the reviews I've found on line, owners of the Bravada like their vehicle and the engine sounds solid. Thanks for everyone's input.

The I6 will NOT fit in the Colorado. The engine itself is too big for the engine bay.

They are not killing the GMT-360 or the 4.2L I6. The I6 has been on the Ward's Top 10 engines list like 4 times. I highly doubt they would even think of killing off an engine with those kind of awards. GM is basically putting it on the back burner so they can do more important things. They did the same thing with the Zeta platform. Everybody bitched b/c they thought Zeta was cancelled, but that was not the case.

Those wanting bigger engines are in the minority these days. What's in my Colorado (3.5-5) gets up & goes pretty well. Folks buy bigger trucks if what you need to pull makes the Colorado sluggish. If the Colorado can't keep up, that means you bought the wrong-size truck. No need for alny of the auto makers to make these smaller pickups like race cars.
