I am also in dilemma between Fiat Linea and Avventura. Decided to wait till the end of year to wait for launch of Avventura and also for better clarity in petrol vs diesel price gap. Right now my idea is, if petrol go for Linea and if diesel for Avventura/Ciaz. I heard 90hp MJD is better tuned in Avventura and Ciaz than Linea. Any inputs from seniors?
