I think moving from any JDM or BolehCar to any European marque would have similar "impact".. unless u have family member's that drive different European cars so you can take time to test them one by one, going for a short 10 min showroom test drive is really too short to tell u much.
I don't have a rich background, so I don't get those opportunity. I took the plunge base on few gathered facts:
1. Alfa is a pure performance car but too raw, less refined. High maintenance!
2. Audi was a little less aggressive in their design.. until lately. But my heart is with BMW lio. Audi market is smaller and that would result in difficulty in sourcing parts, both availability and price. Depreciation also very jia lat!
3. Fiat? Spares also rare and value drop like rocks, short of performance too (minus the Fiat Coupe la).
4. Merc brand is too mature for me. I still can't accept the fact of a 30 years old young man driving Merc. Its either he's very successful, or too show off, or try to impress mother-in-law. I am neither.
5. VW GTI FSI DSG... is another cool car in my consideration list.. but the car is not too suitable for a family man like me... 3-series offer more boot space and more refine ride than the sheer race breed of a GTI. Since young, I never fancy any hatch back car, I call it no back side..
As u can see, I don't have much choice..
