The "poor offers" are due to the fact that the car is expensive because of the beautiful 3.5L VQ engine's road tax. People who can easily afford to pay the road tax would most likely buy a newer car. Plus the fact that it is a beautiful roadster, which isn't exactly practical for Malaysian weather and only truly appreciated when going to Cameron or Genting with the top down.
Considering the road tax is RM4380 per year, insurance, assuming a value of RM75,000, would be ~RM2250 approx. That's RM6630 a year, before you even drive the car. Throw in some service, some tear and wear for an old car, its advisable to put RM10k aside for the car each year. This is not including the installment for the car yet.
So let's assume we can get 3 years loan for the car, at 90%, car sold at RM75,000, 3% interest, that's a monthly installment of RM2043, add in the sunk cost for the car (RM10,000/12 = RM833) = RM2876/month
Naturally, people will look at their options, for purpose of illustration I have a 2 door roadster with reclining roof
VW EOS, RM257k, 90% loan, 9 years, installment is ~RM2459, 2L affordable road tax
New car, warranty coverage, cheaper operating costs.
And bare in mind the car will be 10 years old next year. So to make up for the expensive road tax, naturally people make lower offers. It's a lovely car, no doubt about that. Hope this helps.
