Some correctionI like the GTI variants. I've driven the Polo GTI and Golf GTI, both are awesome cars. The Polo is more insane than the Golf though, that much power in that tiny car!
Bored with the Sylphy no, feeling underpowered yes.
Car preferences are personal la. I find the Mark X a boring car. But that's not true for you since you bought one! I personally hate CVKit17 but the Myvi has killed me twice over because of my statement. And owning 2 1.3 variants doesn't help.
Anyway, if you've guys seen how kcng drives his "Altis" around track, you'd be impressed. I've tested his car for a very short distance and that 1.4 TSI is pretty impressive. He's never had GB issues and the only problem he had was the power window I think. I can't remember. But he's selling the car now which is a shame.
RM90 bucks for roadtax and 14km/L FC is pretty awesome.
Why not sell a myvi and get a polo 1.2 TSI (is it still available?). I doubt the NA Polo will be of any fun. VW cars are fun partly because of the turbocharged engine. Take that away, I think it is a boring car too
