04 vs. 05

I tried looking for something close to what I was asking but I had no luck so...

What is the difference between the 04 and 05 besides the 5.7 and then 6.0
I heard the 04's had some bugs but I could be totally wrong. I just want to know if it is worth spending 3 grand more for an 05 besides the fact that it is newer and has 50 more hp. By the way what ways are there of putting the 04's 5.7 close to the out put of the 05 6.0? Anything else you feel like tellin me about mods and or pros and cons of the 04 to the 05 also tips for buying a used one would be helpful ...Thanks

'05 has:

- LS2 Engine versus LS1
- Larger brakes (significantly larger) with painted calipers
- Split dual exhaust (instead of both pipes exiting the driver's side)
- Hood scoops (non functional)

The LS1 5.7 engine is a very nice engine with tons of aftermarket mods. It can easily be made to make more HP than the LS2 (with money of course, and a voided warranty). I think the 2005 or 2006 would be the better bet, but the 2004 is still very nice.

As for the bugs, I see more 05's come through my shop with software issues than 04's. (no offence to any owners)

2004, .588 lift cam, slp LT's, ported/polished MAF case&throttle body, CAI, Flowmaster Deltas, B&M shortthrow, dragbags, HP Tuners tuned.

I've owned my 04 since 6/04 bought it brand new. The only problems I have had were minimal. The door lock actuator needed replace on drivers side and a plastic cover on passenger side under dash came loose and was replace all under warranty.

The 6.0's are a little faster....not significantly. Seriously speaking though, how fast do you want to go from red light to red light?

The 0-60 is part of the measurement of the performance of the car. I wouldn't purchase a car based on..... is it much faster than the other? Unless of course if I planned on racing it.

Used 04's are bringing pretty good resale prices, and so are 05's.

As far as options, there are numerous changes from the 04-06's. They all get up and GOOOO though, and the 1/4 times are not that significiant . The check book is what I base my 0-60 times on.

a full bolt on ls1 will get to about what an 05,06 will put out. I dont think it would void your warranty, depending on your dealership, as you wont be changing the internals.

long tube headers
cat back system
cold air intake
underdrive pulley
and most importantly ...a good tune.

by the time you spend the roughly $3000 for those mods, might as well by the 05,06. by the way, the prices are NOT installed prices.

Mine is an 04. I just feel a little more comfortable knowing that my gas pedal is actually connected to the throttle body and a software gremlin isn't going to mess with me. I'm not too sure about that fly by wire stuff.

Love your avatar - can you teach my dog how to do that? I also have a MB 04 and love it.

also - for the record, I have never driven an 05 or 06 so I couldn't comment on the seat-of-the-pants difference between the 04 and 06, but I do like the lack of non-functional hood scoops on the 04.
