SLK320 Low Power

[Air&Road]

I have been looking for a manual transmission 2001 SLK320 for several years and bought one today. I don't pick it up until next week, but want to get input about the low power problem.

The car is absolutely pristine in every way. Everything works very well. Has 38,000 miles. No light on, and haven't been able to check for codes yet. The engine sounds great, runs smooth, but is noticeably low on power. My first thought was the variable length intake. My brother in law, a 25 year MB dealer diagnostic tech, said the mileage was so low that the intake runners are probably not the issue, but this was via text and I haven't talked to him in depth yet. I am anxious to draw codes, but I wonder if anyone has any experience with this problem.

I am excited about the car even with this problem. The car is outstanding in every other way and I bought it worth the money, so I am willing to work through this problem.

Thanks for the thoughts and comments from those familiar with the breed.
