Q. Is base petrol model good - Rapid?

It carries all the basic attributes like superb built quality, great handling, but has no features. some features like steering mounted audio controls and auto air-conditioning can not be aftermarket.

Yes, it's also good but as Skoda has better built quality usually petrol models loos out on fuel economy. if you are not worried about fuel economy then it's a great car with lesser year on year maintainance than diesel and good on refinement.

Its purely an individual decision but would not rate Petrol model above diesel. Skoda diesel is a superior engine.
