Question for all you high mileage guys...debating about selling my '06 C230

I figure my car is worth about $10k at the most and the SL500 would be around $25-$30k vs. a newer C class for about the same $$ with the trade.
One side of me says get the SL and drive them both, basically splitting the amount of miles a year which will cut down the major repairs a little. But the sensible side says that I'm only going to have bigger bills with two older cars in the garage..
What should I do? If it makes any difference, I am the original owner of the C230 and it's in really good shape in spite of the miles. Almost all are highway.
Thanks!
i got an 06 c230 with about 77k and i'd be glad to take $10-12k. youre lucky if you can get that much at your mileage. i just feel that the demand for our cars plummeted since the w204 facelift, but thats just me ranting about wanting a new car.




The W205 is on the horizon, you might be able to score a good deal on a W204...
If you're concerned about high maintenance costs a 03-05 SL would be like shooting yourself in the face.
I say keep the W203, or trade for a W204 if you must.
Having two daily drivers is like having two wives; in theory, it sounds good, but will end up being twice the headaches.

Did you ever check to see if your engine is in the serial number range of engines that may be affected by the bad balance shaft sprocket? You have the 7G right?
You have already taken care of 2 common and fairly expensive repairs for you model, the manifold and fan. Plus, you maintain it well, so I say keep it. Just cracked 103K on mine today, and still have no desire to get something different.

I can handle the routine maint. on both and the "toy" won't get enough miles each year to cause any major issues. I would also buy an aftermarket warranty for the toy so any big ticket item would be covered.
If I lived in CA or FL, I would get the SL as a daily driver in a heart beat, but it just does not work here. I'm also looking at it in that with the value already being under $10k for my car, how bad can it be in another year or two?
I have a couple of questions re: high mileage --
1) Is there a high mileage oil for these (M271) engines? If so, what is it and at what mileages should I switch over?
2) When do the trannys go out on these? My prior car was a 1999 BMW 540, the transmission gave out at 90k miles. For a $5k repair at that mileage I wasn't pleased. In the C230 it feels like a bit of play is developing in there -- should I be concerned?
Thanks. John

2) The 722.6 is a robust box not known for giving much trouble. There is an occasional speed sensor failure but overall failure of the transmissions are rare. Changing the fluid would likely help clear up the slop you mention. My car at 141,500 miles still shifts fine, if a bit firm between 1 and 2nd. I changed the fluid at 100k miles and flushed it at 120k. I plan to do it again around 160k.

And not everybody takes out a loan for their car. I could take out a loan and get an e63, but that would have a bigger effect on other things of importance. House, wife, golf, etc.
