Having the similar dilemma too, wife driving 308 VTi & it's super sluggish when goin uphill... That kinda put a doubt in me on the car evnehtough it comes with 6speed if I'm not wrong; polo instant addicted but then again.. The space is a turn off

Few of my friend owned vw having prob with the gearbox, both golf & gti not sure abt polo though. Friends' 308t having probs with gasket & engine oil leak (3of them for the record purpose)

So for TS, I can't help but me myself in the same situation as you
