I thought I'd elaborate a little on my original post.
Malaysia is perhaps one of the places on Earth where cars are very highly priced, compared to GDP Per Capita etc etc.
As a point of reference, a (admittedly highly specced) W212 E300 Avantgarde today costs approximately US$140,000, on-the-road without insurance.
I don't know what it costs in the US, but I'm quite sure it does not cost that much.
Consider also that the Malaysian GDP Per Capita is US$14,800 (cf. the USA at $46,900) and you get an idea of how 'luxurious' a proposition owning a Mercedes Benz in Malaysia is.
Given this, a 10 year old W210 E240 that can be had for $30,000 or less represents very good value, considering the build quality, and high level of features found in the car.
The other key 'value' factor relates to maintenance and cost of ownership - in that, especially with the older MB's, spare parts are affordably priced, and there are many workshops and service centres (non-MB) who can tend to these cars perfectly well.
While cars like the Lexus (which have only recently come into the market here - Toyota's are really the common brand in this country) may be very well built automobiles (we'll put aside the issues of late with accelerators etc), they are not yet widely found/established to have a solid 'service community' - therefore, ownership/maintenance of a Lexus comes at a high premium.
In the context that I'm providing then - the value I speak of relates to the older but well maintained models - which give great value for money.
Yes... the prestige element comes into the mix of course.
If you could have a used MB in great condition for $30k, or a new Toyota Camry for $50,000 - which would be the more appealing option? ... assuming you're not hell-bent of having a new car of course!
Me? I'm loving my 'old new car'!
Value means different things to different people, but if it is reliability that you want, you are sipping at the wrong well with either MB or BMW. You want reliability in the higher-priced brands, you want a Lexus or Infiniti or Acura.
