SL55/63/65/R230 AMG: E55 compared to SL65
Remember, once the Biturbos Kicked in, BAM YOU'RE GONE.
(JUST MAKE SURE THE 65 DOES NOT HAVE THE IC pump problem).
R. Range
If possible keep the e55 and get the sl65, get rid of the 06' CLK350 IMHO.

George, that's not a bad idea, and my wife would probably go for that (the CLK is hers), but it's the only car I have that's leased, so dumping it right now would be complicated.

Yes and no. If you take the cost of the 55k car and add 10k in upgrades you will still come out cheaper then the cost of just the 65. Also 100hp may be a bit high to gain. Most guys gain 40-60whp from the ecu tune which in itself is anywhere from 4500-6500 and if you add the only air box on the market that is another 4k. Think it all through and see what you like. There is just way more out there for the 55 motors then the 65 motors. The down side to the 65 motor is you max out the tranny right away with all the lbft. So you can only add very little hp and your done. Where as the 55 motors have the same tranny limit but seem to only add a small amount more lbft for the increase in hp. So you could have a 700-800hp e55 and still not be at max torque. Look at the slr perfect example. Also the sl is a heavy pig which bugs me. At 4500-4600lbs compared to the e55's 3900-4000lbs. If you could get 700-750hp out of the e55 it would be a beast. My car is at 680-700hp depending what kind of dt loss you give it (565whp). I have not tuned the car yet it is just a freak. But if you look at NSM's dyno he made about the same power and he had 794lbft at the wheels so if the tranny can only handle 840lbft then I can only gain 15-20whp and 40lbft at the wheels and I am done? I want to gain 40whp and have 600whp but I dont know where the lbft will and if the tranny can take it.
If you trade the E55, you will miss the seats, the interior room and the long distance comfort!
I can know it......

I guess in the end a lot of it is coming down to whether I'm willing to give up my roomy 4 door for a 2 seater. Don't think there is a "wrong" decision here, fortunately.
I agree there's a lot more out there for the 55k cars, but the 65's start with ~100hp/200ft lbs more than the 55's, and that's a heck of head start to overcome. Getting an E to the numbers for NSM's car with just ECU/TCU mods isn't gonna happen without a big shot of nitrous, and while I agree the tranny is an issue, I bet you could have Renntech strengthen the tranny less expensively than you could buy headers, pullies, ECU tune, exhaust, cooling upgrades, throttle body and all the other stuff it would take to max out an E. And once the tranny is upgraded there would be room for even more boost.

And we have more mods coming out for the 65 pretty soon....
I have (present tense) an SL65.
Both great cars, one has 4 doors, one has a small trunk.
Can't go wrong either way, but obviously I chose the SL.
Good luck.
The only advantage, with regards to your needs, is that it has rear seating which I'm assuming you really want. If that's the case, what do you think about an S63/CL63?
