Both are good cars with very strong diesel engines, Cruze is more powerful with 163 bhp on tap and sportier than Superb. While, Superb is more fuel efficient and more practical with more space on the inside. On the service point of view, Chevrolet has a stronger service infrastructure than Skoda, so it would be more convenient to own Cruze. Also, before finalizing get both the vehicles inspected by some expert mechanic so as to make sure there is nothing wrong with them. Do ask for the service history of the car you wish to finalize.
If we look into the dimensional data of Swift, it is approximately 1.7 meters wide (very less than 8.5 feet) and it is less than 4 meters long (again less than 14 feet), so it will easily come into your parking area and still leave space for you comfortably pass through and open the gates quite easily. As far as i10 is concerned it is smaller than the Swift so i10 will also fit in comfortably.
