Toyota Corolla 2004 Problems

The damage seems extensive, and being an old car I would say it isn’t worth fixing.

No, it’s not normal, but it doesn’t mean it’s a lemon. It might only be a minor problem, so have a mechanic check it for you.

First you need to know the total weight of the trailer when it's loaded with everything you want to take with you when you go camping. It could easily sneak up to close to the Corolla's limit of 950 kg. You have to think of safety when towing, and it doesn't matter that you will only tow short distances or do it twice per year. I would tend to go for the Camry, it has a higher towing rating, it is a heavier vehicle and therefore more stable, and I think safer for your needs.

Hyundai claims an average fuel consumption of 4.7 L/100 km for the i30, with 4.1 L/100 km in extra urban driving and 5.7 L/100 km in urban driving. The fuel consumption figure used by Hyundai, and all other carmakers, is derived from the standard test conducted in a test laboratory, not real life. The purpose of publishing the test result is to provide buyers with a means of comparison between makes and models, it's not really meant to be taken as a real life measure of what you would get yourself. But it shouldn't be too far from the mark either, and I would reckon a 50 per cent variation is too much. More to the point you need to take into account your driving conditions, do you drive in flat or hilly conditions, do you have a lot of stop-start traffic on your way to work, do you mainly do short trips. The consumption you get is on the high side, and you could ask the dealer to check your car to make sure it is running well, but I believe the problem will be environmental.
