If you need a vehicles by which you could set of for cruises, which could hold more things in the boot , go for the Opel Tigra I. The Lotus Esprit is equiped with by 15 l smaller luggage compartment in comparison to the Lotus Esprit 2.2 S3 162HP so probably in this case you would be able to load a bit less. Examining the trunk also pay attention to its dimensions which have notable impact on loading possibility .
Opel has 29 millimeters longer wheelbase than the Lotus Esprit. A longer wheelbase provides more stable and comfortable ride, especially when driving fast. It also gives more storage space. However, cars having a longer wheelbase will not be as maneuverable as those with a shorter length between its axles.
Number of doors
An owner of the Opel Tigra I has a one door more at the back of a car. It will enable him to load and unload stuff into a boot in easier manner, especialy when we are talking about things of large size. Passages of both cars who are to travel in the rear need to enter a car through a front door which requires folding a front seat.
The higher a car is, the the more convenient is a boarding it and greater capacity of putting big amount of stuff to it. The difference between these two cars at the level of 17 percent in favor of the Opel is insignificant and should not be really noticeable.
