2005, Honda S2000
2005, Honda S2000
I have never enjoyed driving as much as I do in this car! And I only paid $24,000 for it (1 year old, with 16,000 miles, perfect condition). It's like the car I always wanted. I had always wanted a porche, but could never afford it. This car is as much fun as any Porche, and according to Car & Driver, it outperforms the Porche Boxter. It has a 2.2 liter 4-cylinder engine that is very manageable for daily driving if you keep the RPMs under about 5000. But it redlines at 8000! Once you get over 6000 rpm, it screams like you wouldn't believe, and presses you further back into your seat! The ride is too harsh for most people (especially most americans) to use every day, but I don't mind it at all. As a result of the very tight suspension, it handles curves like it's glued to the road. I even drive it all winter in Michigan! In a comparison test by Car And Driver in 2003: Fifth Place: 2003 Audi TT Roadster Fourth Place: 2003 BMW Z4 Third Place: 2003 Porsche Boxster Second Place: 2003 Nissan 350Z Roadster First Place: 2003 Honda S2000 Car and Driver said: Haring around is not the mandatory driving style in sports cars, but to qualify for the class they must be capable of it. And if you drive this Honda politely, you'll never know about its other moods. Ride harshness is Boxster level, but the car feels much crisper. Weight is less by 189 pounds, and the controls are sharper. The clutch stroke is succinct. The stubby aluminum shifter travels in microflicks. Precision machinery, that's the feel. And if you keep the yellow graphic arc of the tach below, say, 6000, this Honda plays the sweet little zip-about roadster. Above 6000, no more nice little Honda. The VTEC cams switch to HP max, and the sound hardens to combat steel and you're in the full Formula 1 mode, hell-bent on a grid position at Monte Carlo. Default to fighting reflexes. Lead the arcing yellow as you would a low-flying clay. Don't wait for it to touch the nine-grand redline; you'll be into the rev limiter. Pull. Snick! Push. Snick! Pull. Snick! Check the mirrors for flashing lights! Whew. How long can you keep living like this? This is a scalpel-quick sports car when you keep it boiling, quickest of the bunch around the BeaveRun road course, barely behind the Z4 in acceleration, even though it gives away a full liter of displacement. Think intensity. Think fury. Think...could I stand this as an only car? For sure, only an extremist would love it as an interstate cruiser. And yet, and yet . . . so much excitement for a fraction of Porsche and BMW prices. Actually, the Honda's interior details, particularly the leather wheel, look richer than the Porsche's. The metal-trimmed pedals and footrest fit the racy personality exactly. According to RS Sports Cars: Widely considered the quintessential roadster-style sports car, the S2000 is the performance icon for the Honda brand and combines uncompromising racetrack-ready performance with everyday usability. Introduced in 1999, the S2000 rewards driving enthusiasts with a potent 237 horsepower, 2.2-liter, 16-valve DOHC VTEC 4-cylinder engine and a precise, short throw 6-speed manual transmission, along with tenacious handling and a perfect 50/50 weight balance. Continuing with significant improvements made to the 2006 model, the 2007 Honda S2000 includes an electronic Drive-by-Wire (DBW) Throttle System, Vehicle Stability Assist (VSA), "The Honda S2000 is a true performance vehicle that provides customers with an exciting experience behind the wheel," said John Mendel, senior vice president of American Honda Motor Co., Inc. "Since the S2000 is a car designed by enthusiasts for enthusiasts, it can easily satisfy daily driving needs without sacrificing track-worthy performance." The S2000's renowned high-revving, 2.2-liter, 16-valve DOHC VTEC 4-cylinder engine remains the pinnacle of naturally aspirated performance technology, delivering 237 horsepower at 7,800 rpm and 162 lb-ft of torque at 6,800 rpm. Perfectly complimenting the engine's output characteristics is a compact, longitudinally-mounted, close-ratio 6-speed manual transmission that features a direct linkage for precise shifting and quick throws. The S2000 comes equipped with a Drive-by-Wire throttle control system eliminating the need for a mechanical connection between the throttle pedal and the engine. This enables continuous electronic monitoring and adjustment of throttle pedal sensitivity to create an ideal match between throttle response and driving conditions. The system also manages the S2000's cruise control function for greater precision. Honda's VSA system makes the S2000 more stable and forgiving during street driving or in inclement weather conditions. Working in concert with the Drive-by-Wire system, VSA continuously monitors yaw rate, steering input, throttle input, and braking pressure to determine if the car is following the driver's intended path, and can independently coordinate each o

I drove out to the end of the Ohope peninsular in my 1938 Morris 8. I now have hardened valve seats (or something) so can put regular fuel in without additive. Suits me just right. Can't go wrong :-) Plus I have a modern engine in it now, 1939 I think! Still have the 38 engine but it's got a few cracks. Will save it for posterity or maybe someone will want it later. No it's not junk!!
