There's pros and cons on Jetta. The pros being that it is a continental car and you can expect a good NVH from it. Also the DSG gearbox is superb. If compared to Optima K5, the latter offers alot more gadgets that you can play with. Sunroof/moonroof, paddle shift, keyless system, Infinity sound system and not forgetting all the safety features it offers and larger space for rear passenger and huge boot size, with the jetta at around RM 10k more pricier. If you don't like gadgets and prefer good NVH, then go for jetta. If you want more value for the price you pay, then you should consider Optima K5
