It seems like I’m often talking about what the best performance deal going in German cars is. That’s partially because I’m not partial to paying the “what’s new” tax on the biggest and baddest new car. Personally, I’d prefer to let someone else take the substantial depreciation hit and when it’s no longer new, swoop in for what’s still (to me) a pretty new car in good shape. The other part, though, is that I’m not flush with cash; perhaps if I had limitless resources I’d be at the Porsche or Audi dealership every other year signing on a new car. Regardless, there’s a huge contingent of our readership that I believe is in a similar situation to me – hence why we tend to look at older, more affordable (most of the time) models that represent good value, performance or collectability for a more modest investment. That brings us to the car at hand; in this post’s case, a 2005 Porsche Boxster. 2005 was early into the 987 production, having replaced the 986 in 2004. By most peoples’ measure, the 987 was a better looking car, mimicking many of the styling cues of the 997 as the 986 had mimicked the 996. Performance was also improved from some new motors, including an upgraded 3.4 liter engine in the S producing nearly 300 horsepower. That motor, however, did not appear until 2007 – meaning the top-tier S model in 2005 still had the 3.2 from the 986 sitting in the middle of the car. That motor was good for 276 horsepower, which by no means was a small amount. For some people it simply wasn’t enough though, and as expected German super-tuner Ruf offered the solution. The modified Boxsters went by the names of their engine displacement; in the 986, there was the 3400S, which was replaced by the 3600S. When Porsche introduced the 987, Ruf responded with the limited run RK Spyder and Coupe with a supercharged 3.8 liter flat six good for an astonishing 440 horsepower. That was in turn replaced by the 3800S, which it still available. With the newest edition of the 3.8 flat six producing over 400 horsepower (more than double what the Boxster had at launch), Ruf turned the entry level Porsche into a supercar killer:
