Mind sharing with me your calculations for both the models?

Bro, you can't take two different segments to validate your statement. A young man starting out is highly unlikely to consider an old D-segment for various reasons, including high FC, high maintenance costs, higher road tax and an uncle image, among other things. A cheaper to maintain C or B segment car is more suited to them. As such, D segment cars tend to depreciate more than a B or C segment car. And, once you see the rough calculations I did below, it will change a lot of perceptions. I must admit I too was shocked at the results. Do indulge me:

Let's compare the following D segment cars:

2003 Camry 2.0 (the big backside model) New price = RM140k
2003 Sonata 2.0 New price = RM110K

2003 Camry 2.0 now = RM55k
2003 Sonata 2.0 now = RM25k

Camry's residual value = (55/140) x 100 = 39.28%, depreciation = 60.72% or RM85k
Sonata's residual value = (25/110) x 100 = 22.73%, depreciation = 77.27% or RM85k

So at the end of the day, what does it tell you? If you take away the percentages and other figures and look at the bottomline, both cars lost RM85k over a span of 9 yrs, or a flatline depreciation of RM9,444 per annum.
