Keep my '05 E500 or trade it for '07 E320 Bluetec
I have currently the opportunity to change me '05 E500 (95k miles) for the '07 E320 Bluetec (75k miles).
Well, I have the problem if I should go with this or not. I love my E500 - it is a great car, but I am European and I like the new Bleutec diesel engine, too.
Will appreciate any opinion or suggestion.
BTW, how much you guys think the '07 E320 Bluetec RWD with 75000 miles should cost?




I feel like I will keep my E500 (I do not drive more than 15k per year) but next weekend I will have the Bluetec for a couple of hours for test and then I will have more information for the best decision.

Of course, it's really none of my business! Simply trying to find out if you are a D2 Nut like me?

Get the CDI for mileage. Not performance.

I terms of everyday all around performance, that V8 is simply not in the same ballpark!
I would much prefer 369 ft/lb torque at a useable rpm that less torque at a much higher rpm!
My E-320 CDI supposedly has 369 ft/lb of torque from 1800-2400 rpm.
In other words where the tachomter spends most of its time.
The E-500 V8 puts out only 302 horsepower at 5600 rpm (way higher than most people rev!),
and more importantly, makes its maximum of only 339 lb-ft torque from
2700 through 4250 rpm. There again, much higher than most people normally rev their engines.
Fuel economy is nothing to brag about either.
EPA Fuel Economy is only 17 city, 25 highway miles per gallon.
Tank mileage should be approximately ten (10) mpg higher for the diesel.
Bluetec V6 Diesels have 208 horsepower. That alone won't impress anyone, but it is the
400 pound-feet of torque, available from 1600 to 2400 rpm, that will!
Drive the E320 within that huge torque band, and you'll leave others standing.
Its midrange passing power is phenomenal, and the seven-speed automatic trans offers a ratio for every occasion.
With that transmission, you will most always be within those rpms.
You will find that in the long run, you will be better off with the diesel over the gas hog.
Diesel E-class cars keep their value whereas the gassers do not, especially the V8s.
Priced the cost of new air-ride shocks for that E-500 lately?
Time to trade now before you need those $1K per corner wonders.

Just a few things to think about.

I think the caveat is that if you time things right for a certain duration of time in the right RPM band you have phenomenal torque for passing. It seems a great alternative to the V6 but does not seem to offer the constant and smooth power delivery of a V8.
I actually think it is a shame that the Bluetec is not offered with 4MATIC. If they did, I think a lot of the E50 4MATIC sales would suffer as I bet many would opt for the fine diesel engine.

0 to 60 MPH and Quarter mile times vary depending on which magazine you read.
It's hard to explain . . . but when you drive any late model MBZ diesel, be it my 2005 CDI (preferred to me!)
or the newer more choked off Bluetec (DPF and AdBlue fluid), the performance of those tests
do not speak properly to the way the cars actually feel while driving them.
Sure, in a so-called acceleration contest, the diesels are a tenth or two of a second slower, but
that does not tell how they really perform when driving them in every day-to-day conditions.
When taking off from a dead stop at a traffic light, it is surprising how the traffic
behind you simply falls away if you want to 'get with it' so to speak.

i.e. You want more power when starting up a grade?

With the diesels, you simply ease down on the throttle just a little bit,
and the car charges up that grade like there is no grade there at all!
That is because of the high torque that is right there at the rpm where you already are.

With the gassers the only way you will 'charge' up that grade is to drop one or more gears
and rev that motor to get the engine to put out enough torque to gain speed.
With the diesels, you are almost always in that maximum torque band where downshifting is not
necessary. With the gassers, you must downshift, and in so doing, there goes fuel economy.
In that same manner, when you need to pass, you do not have to floor the throttle to do so.
You simply ease down, and away you go.
One of the reason that tank mileages, at least for me, are always in the mid to high thirties.
Guess you may figure which engine I prefer, this 2005 CDI being my eleventh MBZ diesel.
