Mercedes Benz W203 2001-2007 worst merc to buy ever

Mercedes Benz 2001-2007 with M271 or M272 Engine - Don't buy it second hand
Let me defend myself first. I am a merc fan. If I thought it was an investment I would buy a new one, but it happens that I know a little more about money since school days and realized that a new car is a waste of money.

I started looking for a good second hand car


This had led me on the adventure of looking for a good second hand car that is comfortable and reliable. Another important factor is fuel consumption. It must be low since I am in no mood forking out half my salary in fuel costs.

The C-Class size fits my requirements perfectly so I started looking at various models and technical specifications. I was quite baffled at the amount of information that is available on mercs compared to other vehicles which is great if you are planning to buy a second hand car and do some of the maintenance yourself.

I think the best source of Mercedes videos and information is https://mercedessource.com/. I think Kent is very realistic and has enormous knowledge of these vehicles and its worth visiting his website and his YouTube channel.

Shock and no awe realisation


My enthusiasm started to dwindle when reading about the problems caused by the M271 and M272 engine. The big uproar and hooha is caused by a fundamental design flaw resulting premature wear of timing chain sprocket for the balancer shaft. If the sprocket wears of and the timing chain slips, it results in the death of your engine. The cost of fixing it can quite often be the price of a second hand replacement merc and many people considered selling their cars for scrap. Yes it is that expensive to repair.

A complete list of M271 engines and in which car it was used can be found on AustralianCar.Reviews website.

So the following Mercedes Benz C-Class 2001-2007 models are a sure no go if you want to buy them second hand:

  • C180K 1.8L 143hp Inline 4 cylinder (I4) M271
  • C200K 1.8L 163hp I4 M271
  • C200K CGI 1.8L 170hp I4 M271
  • C230K 1.8L 170hp I4 M271
  • C230 2.5L V6 204hp M272
  • C280 3.0L V6 231hp M272 
  • C350 3.5L V6 272hp M272

The above mentioned cars are all duds. They will drive nicely until you reach ±150,000 - 200,000 km, and if you are not lucky your engine will go bang.

So if you want the petrol C-Class merc, you need to budget the replacement of the timing chain into your maintenance cost and also into the price of the car.

The best option, if you really want the C-Class W203 Mercedes is to go for the diesel versions, either the 220 or the 270. They have their own problems but not as big as the M271 and the M272 engine.

At the end I might as well buy a Toyota 
Update: 2017/09/26: eventually I purchased a Toyota Corolla Quest which is a far better deal any old can ever be

Merrell hiking shoes showing cracks in quality

Image
Merrell Hiking shoe's quality start cracking up I have been a supporter of Merrell shoes for quite a long time, actually about 10 years. Their comfort was amazing as well as build quality. My first pair was hiking boots and I wore them until they fell apart, I must admit that the sole wore through before the top started coming apart.  I then bought hiking or trail shoes. I think the style was Merrell Vibram, not sure but that was written on the side of the hiking shoe.  Anyway, who cares, I don't hike or go on trails.  They are mainly used in and around at home. I also don't do any gardening with them by the way. So all in all I don't have a lot of wear and tear as can be seen on the amount of rubber left on the new pair of Merrell Hiking shoes. What really disturbed me is how badly the new Merrell Hiking shoes are put together. Put it this way, my old Merrell's had 5 years of walking on them, and there is not much wrong with them other than the

Fitbit Charge HR inaccurate heart rate measurement - personal experience

Image
Fitbit Charge HR inaccurate heart rate measurement The Fitbit Charge HR claims to be a fitness device which can measure various aspects that people deem important during training.  There are two parameters that I think are important when training. (1) Your heart rate and (2) the number of steps taken.  I think these two parameters are the only really accurate measurements that can be trusted to measure your intensity and duration of an exercise. Other parameters like stairs climbed, calories and GPS are really not that important. In any case calories are derived from your build and heart rate. The main reason I purchased the Fitbit Charge HR is for its heart rate measurement. This turned out not just to be an utter disaster but also extreme frustration and disappointment. So why am I making these claims. Well let's see what my average gym routine is every second morning: I start of with 20 minutes of "arm cycling". Have a look at the machine here . I run it

Fuel consumptions of a 1999 Polo Classic 1.6L manual petrol

VW 1999 Polo Classic 1.6 Manual Petrol fuel consumption data For all those who want to know what fuel consumption a 1999 VW Polo Classic sedan will give can get the real info here.  Most driving was done on 70% highway and suburban traffic. None was done in city driving or peak traffic time.  The car was never pushed above 120 km/h or 75 mph on the highway, actually, most driving was done at 100-110 km/h (62-68 mph). So far the average fuel consumption for the Polo Classic 1.6 is 8.6 L/100 km or 27.35 mpg (US) and 32.85 mpg (UK). Which considering the car is 18 years old quite good. It hope this will help a lot of buyers considering an old car like this. We all worry about fuel consumption and anything above 10 L/100km or below 22 mpg(US) or 28 mpg (UK) is considered high.  I must say I was quite surprised how low it was, especially the mileage done. The car does use some oil, but not a lot. We have to add about 500 ml every 4 months. Date Odo reading Trip Fuel added
