W202 is a bullet proof and a perfect driving machine.
Unfortunately you cannot buy a 0 meter W202 now and most previous owners have abused it in Pakistan, I know some who have even tried to run it on CNG and messed up the engine.
So a W202 can be only as good as its previous owner has kept it.
Parts are surely expensive for genuine ones, but are easily available and made in China ones are also available that works fine at a fraction of cost.
A clean W202 needs no parts if it had been kept properly.
You have to use a High Octane Petrol, at least 90 RON from Shell.
You cannot leave it on driver and you cannot drive it on rough roads and potholes daily because the suspensions are expensive.
W202 rides as good as a magic carpet and handles as good as a poor men's Ferrari and it has a build quality like a mini Rolce Royce Phantom.
