I saw LSM's reply but here is my dua sen.
There is no Mercedes "black top" engine, it is probably the M271.
sosIt has basically 4 variations:
1) 1.6 kompressor (super charger)
2) 1.8 kompressor (super charger)
3) 1.8 CGI (turbo)
4) 2.0 naturally aspirated
2002 Mercedes-Benz C-Class (W203) C 180 KOMPRESSOR, C 200 KOMPRESSOR, C 230 KOMPRESSOR

2007 Mercedes-Benz C-Class (W204) C 180 KOMPRESSOR, C 200 KOMPRESSOR

Just incase you're wondering....
There is no "2.0 kompressor" it is either one of the engines above. The difference between C180/C200/C230 is usually the additional accessories, features and tuning of the engine for more power -- basically the mechanicals are the same. I know some people going to feel short changed thinking their C230 is no better than a C180 but think about it the engine capacity doesn't matter to you driving it, what matters is the power when you press the pedal and enjoying the features/accessories in your car (everyone knows C180 is most basic). But the fact of the matter is having the same engine and gearbox means lower running cost as parts are common between many models. Plus when warranty is over just tune it to get more power
Unfortunately leaking engine and mitsubishi tak berpisah especially for the 80s & 90's era
So what kind of budget you're looking at for your SUV/Crossover?
Pre-FL = before facelift
2015 Nissan X-Gear - i think this would fit you as it is within budget (67k), if you want to consider a new one wait around for promotions as the normal price is about 90k but usually promotion like the coming Raya sales you might see it drop to around 80-85k depending on their desperation. Nissan's usually practice this throw price policy that's why their cars resale value isn't as good because even if their normal price is 90k but if they always throw at 85k then it becomes a market normal thus people have a hard time selling used cars above 75k even a year old with warranty because too close to the new car price. Back to used cars, you can look around for the year and model you want, this particular advert seems to be advertising the full spec version with touch screen and leather seats -- don't expect too much from X-Gear it is not a luxury type car it is the cheapest C-segment in the Nissan range you can buy new (maybe other brands also dun have a c-segment at this price). The engine is cheap to maintain and capable but it is not very powerful, full load of luggage and passengers for a vacation might make the engine feel sluggish but for everyday soccer mom duty it is very capable and nippy. While not as high as a pick-up or SUV, the seating is higher than sedan cars. I think such a car strikes a good balance between price, maintenance cost, accessories, age of vehicle and requirements met.

Thx, so it turned out to be a c180 elegance 2.0l. Despite that, I decided to take it since the engine, interior and gearbox r running good. Another question arises as to the interval of servicing. Also can any sifu recommend good service center for MB. Thx a lot
