Hi Calvin,
Regarding the offers you are getting on the Fiesta, please do contact some of our new Fiesta owners on the forum such as hormaz who have bought their car from Cauvery Ford. Seems more or less the same to me, but worth asking them too.
As for after-sales experiences, i bought my Ikon Flair from them last September, and my experiences have been mentioned on my Long Term ownership thread, the link being :

There under the heading 'After Sales Experiences', you can find the required info. Hope that helps.
