Hey sgmane - Like Saket pointed out, I am a happy Skoda owner, however I do not own a Rapid. I have an Octavia L&K 1.9TDi.
Now, there are hundreads on threads on how horrible the ASS of Skoda is. From the last 3 years I never visit any of the Skoda guys for service. I go to United Motors Bosch Service which is at West of Chord Road. Dhiren is the man who runs the show and attends to my car always personally. A lot of high end cars come to him especially after that 3 year period of a car.
I have personally been extremely passionate about cars from the last 20 years...in other words I pay a lot of attention on my driving, taking care of them and a whole lotta stuff. Maybe we can have a chat sometime on this as I can go on and on about this Octy beauty.
In my opinion, these cars are not designed for Indian Roads and its conditions. They have to be dealt with very differently. Example: This cars service is due once in 15000kms but I get a general checkup with air filter cleaning every 4500kms and change the Oils at 12500 and dont wait till the 15000kms mark.
Spares are quite expensive but with Bosch, it aint as expensive as the guys from Skoda Service.
Hope this helps....
