"... As for maintenance, if you read the specs, the "severe" interval for the NA cars is 3,000 miles as well, so the oil changes are probably not even an extra cost. If you drive the car hard, sit in traffic, take short trips, etc. Those are all considered 3k changes even on the NA cars. "
  
So under the same driving conditions, just maintain your turbo like an NA and you should do fine, right?
  
"... Caring for Subaru Turbocharged Engines ... The following information updates factory recommendations for the care and maintenance of new Subaru turbocharged vehicles... Due to heat generated by the turbocharger and carbon deposits contained in exhaust gas, the oil in a turbocharged engine will deteriorate faster than the oil in a naturally aspirated engine. Therefore, special care should be taken to use proper grade oil and to monitor oil deterioration. Under normal driving conditions, the recommended oil and oil filter change
interval for turbo vehicles is every 3,750 miles or four months, whichever comes
first. However, for vehicles driven in conditions beyond normal, such as racing
conditions, the oil and oil filter may require more frequent changing... Any driving where the engine speed is kept high – either by using lower gears at higher speeds or using engine braking – is considered racing-type driving. A “track day” or autocross event requires an oil and oil filter change immediately before and immediately after the event.... Carbon deposits produced by a turbocharged engine can accumulate at the bottom of the oil pan. When changing the oil, always drain the oil through the oil drain plug hole on the oil pan..."

That's all pretty vaguely written. So what's "more frequently than 3750? 3k? I always change mine at 3k-5k miles on my cars and no issues. Heck my 94 turbo legacy went 150k miles with 10k+ track miles (6000 rpms for 2hrs at a time) and never burned a drop of oil.

Don't even get me started on speeding tickets. I went almost 20 years without getting one and then got two in the span of a couple of months after I moved out to the land of photo radar. The first ticket was for going 23mph in a 15mph zone I even went to court on that one and while the judge was very sympathetic, he still found me guilty. can you say "revenue stream"?
 
To keep this post on topic though, I don't think having more HP increases your chances of getting a speeding ticket, although it does get you to the speed limit faster. The key is to know your speed and keep it below the photo radar's threshold.
 
Interestingly enough, both my wife and I have discovered that it's easier to speed in the XT than the SLK. Uh oh, I think I just made an argument against getting a turbo

P.S. Yep looks like we'll be moving to DC next April.

On that photo radar, what band radar do they use? I'm assuming X, K or Ka, and is it detectable by a radar detector? If so it should be easy to avoid tix on them.

Hmmm, good point. I gave up my "Fuzz Buster" over 20 years ago but it may be time to look into them again

8mph over the limit?
 
Here they are everywhere, plus my old detector would false a lot. A ton actually.
 
Not to mention they're illegal in VA, which I go to on occasion.
 
I dunno, Frank, the wife used to get a lot of tickets with her old V6 sedan. She dropped to a 4 cylinder Legacy and didn't get a single ticket in 7 years.
 
Definitely driver's fault but the extra power sure doesn't help in that regard.

Oh well then, that options out... I'll be living and working in VA.
 
For some reason I thought that radar detectors were illegal in MD? Seems like when I used to drive up I-81, you had to be careful on that short stretch that goes thru MD.

Radar detectors are illegal in both VA and DC. Maryland is not a problem, as they are legal there.
 
Move to MD Frank, not VA.

He'd still have to take it down every day on the way to work.
 
Oh boy, you're gonna hate northern VA traffic. Watch, your next car will be a CVT Prius.

The new dectors are pretty advanced. I just got my first one an Escort 9500i, it allows you to block out a frequency a particular GPS location (has a built in GPS chip) so that you can eleminate false reports like at toll booths, banks etc. There is also a feature to mark speed traps and cameras. It will warn you 1 mile in advance. The GPS also can display your GPS speed which gives you an almost heads up display. There is an even newer version where you can download speed trap and camera info from Escort's website. The GPS also allows it to have speed sensitive radar (if you are going under 30mph it will only warn you briefly since you are likely under the limit)
 
Technology is pretty nifty!

Yes it is, and I appreciate tech gagdets as much as anyone.
 
Around here, though, the traps are EVERYWHERE, so you basically have to slow down all the time, and that's annoying.
 
I try to keep a consistent speed, usually 6-9 over. They nabbed me for 11 over, which is lame since the limit is set artificially low. It's a 3 lane road where I was fined, 3 lanes and 35mph?!
