Cars Q&A

Hi, I own a Wagon R Duo 2007 and am looking to upgrade. Daily travel about 70 to 90 km . Wagon R is comfortable to me as am more than 6 feet tall and it gives decent mileage of 11 to 12 kmpl of LPG. Since the car has run more than 80,000 km I think its time to change. Budget is 5 to 7 lack. I must be able to get in/out and sit in side the car comfortably. Prefer to have good head room, other wise it will be difficult me to get in/out and also the rear view mirror blocks my front view (I experienced this while driving New Honda City, Punto & polo) Some of the cars in mind are New: Ritz VDI ABS ( 1st in my list but...Doesnt feel like an UPGRADE from Wagon R) Swift VDI ABS( Not much head room. Dull interior) Dzire VDI ( Nothing better than swift for a self driven) Used: Honda City ZX less than 20k milage (with LPG fitted) SX4 2009 less than 20k milage (with LPG fitted) Ford Fiesta Diesel Honda Jazz Please advice......
