Don't know about Malaysia, but in some parts of the world, your vehichle is registerd based on weight and engine size. I can see where this could cause a problem, plus just getting dmv to record the proper information would be nice as well.
You are rite about the tax thingy. Over here, we are required to pay "road tax" which is based on engine size, and it goes up exponentially above 3000cc (185ci) or so.
If the reg card says 3.7L, I would have to pay about US$1,600 per year in road tax (which is more than 1-month salary for most of us here).
If it was 2.8L, I would only have to pay US$550 per year.
Thats $1,050 in saving every year for gasoline etc.
I just hate paying more than im required to, especially that its not even my fault.
And of course it would be nice to have the car properly documented as well.
