same dilemma, torn between the 4 chicks:
1) Focus TDCi (RM 124 393; both sedan & hatchback) [5.8l/100km claimed] [6-speed]
2) Polo (RM 113 888) - 5 years warranty (unlimited mileage, but no free service) [5.9l/100km claimed] [7-speed DSG]
3) Polo GTI (RM 132 888 - 3 doors, RM135 888 - 5 doors) - *same as Polo [5.9l/100km claimed] [7-speed DSG]
4) 308 Turbo (RM 118 888) - 3 YEARS FREE SERVICE INCL. PARTS & LABOR [7.6l/100km claimed] [6-speed Porsche]
usage:
travels average 80km/day; urban 80%
main concerns:
1 fuel consumption
2 maintenance cost
3 reliability (on par with vios, city; don't want like proton!!!)
4 till death do us part-type of owner *not changing car till it's time to write off; my previous car all used >9years
now... I'd really love to get the Polo GTI 3-door (a bit selfish considering I have a family, but since I'll be using it to commute alone daily to work & the 5-door model is extra 3k, I guess this should be ok ha ha!) because it's SEXY, AWESOME, SUPER-FAST! tried polo 1.2 TSI & immediately fell in love with it, read reviews on polo GTI it's more awesome (also I read somewhere the 1.4 GTI FC is better than the 1.2 TSI.. please clarify on this) thus badly wants it but it it THE MOST EXPENSIVE of them all... but again, their service is only every 15k right? thus the need for further decision-making process.
then, checked up on 308 TURBO, the specs, extras, MORE-ROOMY, the 3-years free service which included parts&labor & the 1.88% DO TEMPTS ME BAD. the salesperson kept calling for me to test drive it, says I should test it & polo, both & then decide - he seems really confident with 308 TURBO. haven't tried yet, but going to soon but now a bit busy. the downside is i there're many bad reviews on NAZA, not to mention the common saying "what do you expect, it's French, not German"
finally the TDCi - it's the BIGGEST of them all, reliable & proven turbo-diesel & read about it's awesome FC etc. price also is between 308 TURBO & Polo GTI. but then, this is the oldest model in the market compared to the others.
in summary, I think my main concern returns to its FC & maintenance - which 1 should I get, & why?

1. FC - Nothng beats a diesel. These beast is made to travel. I am driving a Focus TDCi, i can step on the gas pedal like a mad man (varying from 120km/h-200km/h) and still return 600km for RM80. It can go over 1000km per tank if you can stand the insanity slow snail driving at 60km/h. Can your petrol do that, except perhaps hybrid?
2. Maintenance cost - They are all conti cars, expect higher maintenance cost than your T & H.
3. It should all be very reliable cars, maybe take some extra precaution and read up on Pug, but Polo and Focus is fine.
If you are high speed type of drivers, the 308 will probably out run the TDCi, due to petrol engine inherently high revving characteristics. Polo GTI is the fastest among the lot you listed. Was lucky enough to meet one with my TDCi in the PLUS highway. I only have one thing to say, don't play with it. Stupid crazy car.
