The 15k caught my attention too, I bought from Trio Mantap, SA is Edward Ong. You can try to bargain the price, but you'll lessen your chance of freebies or what not because I had none scroll up a few posts and you can see what I said to another guy. Although it's old stock, Ford doesn't seem like they're that interested in the Fiesta market, now it's all about the GT, so this MK7.5 face-lift might still last a lot longer than you think. PM me if you want Edward's number.
Mine is barely a month old, so my judder isn't that bad. But yes, you are able to change out the clutch system whenever you feel like it's too bad, just call up and appointment and let them test drive with you. If the person says it's okay to change then they'll change under warranty, if I'm not mistaken you can do that for 5 years.

I've been warned by SDAC PJ before not to exceed the scheduled service period if I want to use the service voucher. So you should hope that the SC you are going to are not so particular about this.
If you worry, then don't buy. I'm not trolling you, because when the juddering and jerking comes, and IT WILL come, you will curse yourself for buying this car.

I went for Fiesta knowing what I will be dealing with, so I have no regrets. I enjoy driving it and I would think of excuses to drive it out every chance I get. I learn whatever I can about the car so I can improve the driving experience and learn to adapt to the DCT characteristics. But that's because I enjoy driving; if you are looking for a fuss free car and have better things to do with your time.....look somewhere else.

Not all Fiesta is problematic, mine is relatively problem free. But if you worry about the problems, better just get a Mazda2/Jazz. A car is not cheap, don't rush into a purchase with doubt in your mind.

As what dares said, don't buy this car if you're not wanting to live with it. I too bought the car knowing the problems, and now I'm not even mad at it. You can try going for  a Vios/Civic/Mazda2/Jazz if you really don't want to handle these kinda things. To me I love the FoFi, it's great around corners, great and looking cool for chicks However, I only hate the fact that Ford didn't exactly QC their Fiesta line properly, so we're living with it now. If you don't want the judder, fork up another 100K and get a Focus or Fiesta ST and maybe it's not that bad, maybe.

maybe

seriously, just maybe

or maybe not.
