I had never driven both the cars. So cant really comment on that, but the V6(in Audi a6/Superb) sounds powerful, accleration and top speed figures are mind blowing. And Superb will not disappoint you in features too. But i asked my friends (who work in skoda service). They said, Superb V6 tdi is a Good engine overall, but they also added that fuel pump/water pump failure can be expected anytime. And servicing with individual mechanic wont be a problem as long as they know what they are doing.
My story, (only general service , part change not included)
1st service (indep mech)- 18k
2nd service(performance automotive,ind garage)- 12k
3rd service(indep mech, fmy frnd)- 8k
So,if you the right person, things will be a lot lot easier with a Skoda
.
What is the price quoted for the V6? if u don't mind telling us.
Drive Safe,
