I can clearly say it was one of the best cars i have used,very stable & amazing fuel economy & one rare car which held its ground at speeds close to 180 regardless of road conditions & a gem engine with its smooth torque. But lets throw the fuel economy part out cos a small spare part(genuine) will cost you 2 full tank diesel,so my opinion dont buy this car if your thinking of making savings/vfm
cos you wont except it has rich car image here in India.
Well you will be holding the car for 4 yrs but what about your avg km usage per month?(so to give idea about costs you mite face)
As for a used Octy in most cases tires would have damages cos owners tend to hammer it thanks to its suspension.
On a personal note i dont think i can judge the Octy you mentioned based on Km & age cos i have come across some hammered ones that were brought back to life & seem(not sure) to be doing very well but costs incurred is another thing.
Skoda service is the downfall for there products(barring Rapid since its rebadged Vento with discount) ,so think carefully before you take the plunge.Am not trying to scare you away from a Skoda but trying to be honest on what to expect from personal experience & people around me.
