Here is some review, i have driven vw polo for 1 month while my polo gti in service center.
Pros:
1)more solid than jap car
2) quite spacious for 4 people
3) automatic window for all 4 door
4) cruise control

cons:
1)high service cost for this segment
2) roof still sound like milo tin
3) engine quite sluggish. If put S mode, it should be better. This is caused by too long gearing, for too small cc car..
4) Parts not long lasting. Proven by my colleague 1.6 polo. His ecu bracket broken & arm rest broken. Suspension, 60k km already got hissing sound. All not covered by warranty. VW said it is wear and tear part.
depends what u consider high cost?

normal service at service center, minimum rm600-700. Major service, can reach 1xxx. Service interval is 15,000km or 1 year..
VW is worth for daily usage if u dont mind cost of service and depreciation. The comfort and safety quite good ... 1 bad thing is warranty claim procedure, their process is very slow.. and some service center have reputation of being irresponsible.

Been driving the 1.6 MPI model for 6 months. Agreed with what you said except that the gear ratio (is that what you mean?). Actually the gear ratio for 1st gear is extremely short, 2nd to 5th are moderately short, 6th is damn long. The reason the car is sluggish in D mode is because it tends to upshift too quickly resulting in low rpm low torque most of the time.

Nowadays they have 3-year free service or 45k km whichever comes first. RMA procedure is really slow and consume lots of time to go SC.

IMHO, the strength of this car is actually the chassis, in terms of welding and manufacturing process. The chassis is notably stronger than most Japanese cars (check Honda CKD welding). Not only that, the ride is also firmer due to the chassis rigidity.

However, for VW CKD models, some materials have been removed/changed. For example, the sound proofing material is totally absent in the boot area. The roof is only filled with cardbox material, that's why it sounds like tin kosong. CBU VW Polo had soft touch plastic.

The fuel consumption isn't that great to be honest. For town drive, no traffic jam but lots of braking due to lots of speed bumps (campus and housing area), the FC is not much difference than my old Persona Elegance: ~10km/l. However, for highway drive, it's much better due to more gears. I think Honda City still wins by ~15% for FC. Vento TSI on the other hand can easily get 20% better FC than 1.6 MPI.
The one you drove is TSI model? For the MPI model, the torque is not high actually. Coupled with the conservative GB mapping, it's actually very hard to overtake cars without changing to S mode or Shiftronic.

Aircond is not bad but nowhere near local cars' ability IMHO. Myvi cools the cabin way faster.

Hi dares. I did PM you six months ago before I bought the car, if you still remember haha.
Last month, I was loaned a courtesy car, a beaten up Polo Sedan 1.6 MPI which was an ex demo car. Guess what? It wasn't as sluggish as our Vento. In fact I could drive all the way with D mode. I suspect there are more than one ECU firmware versions out there.

Er...would like some enlightenment on why hissing absorber sound is an issue. My car less than 40k also have this sound and the handling still the same.

this is not a pro..consider standard accessories...even axia got it..

Mine less than 5k km already hissing haha. But only during cold weather/temperature. Handling still ok.
No. I went for the MPI. Tersadai once because of broken CD player. Yes, you heard it right. VW SC's SOP for RMA is #(*$(*@(*@(. Need to diagnose once, second time to confirm which part, then only wait for parts and install. Three times at least for simple stuff like that. Seriously, even Proton is better in this front.

Basically, most Indian sourced wear and tear parts have very short lifespan and not covered by warranty. Another common issue is the disc brake material, would wrap easily when drastic change in temp. Again, worse than Proton here.

Ah well... I like the chassis and ride (vs other mainstream). But too bad the power delivery is lethargic. If given a chance to choose again, I should have bought a 208 Puretech and keep the old car. 

That's what I mean. Since they both are abang adik, might as well choose the higher tech and better designed one lol. 208 Puretech has a modern engine and much better FC.

well , yes you are right because vento body is heavier, so it depends on your driving behavior
if you go for jazz, the close one that can compare to is polo

Was invited to VW safety driving course for the Vento.
Yeah, I agree on the chassis...  But the power and interior build/features is so meh 

Can use to beli sayur or for rich man (but not filthy rich) young daughter 1st car so as not to lose face because buy Japs. 

Actually it's not the 1st gear which is the issue. If you go manual mode and launch the car, it's actually not bad because the 1st gear ratio is damn short. The issue with this Vento is, it will switch to 2nd gear very quickly in D mode. Can say the 1st gear is only used to get the car moving from stationary. By 60km/h it's already in 6th gear.

Vento / Polo Sedan 1.6NA if drive gently (linear speed - uncle style driving) still ok. Remember, this model is a city car and not like Golf for spirit driving. Like most of Conti cars, pick up is slow and u will feel 1-2 seconds delay before pick up from 1st gear.

Yes. Just a tad better than Campro IAFM only lol.
What kind of FC are you getting with your Vento?
