The answer is that most people don't know what they want. There are no "unacceptable" cars these days and most people consider alternatives. Actually, many cars are clones and a Peugeot (for example) will be similar to a Citroen etc etc. So, it's worth to force visitors to experience many different car offers.
The one thing I do do... which hardly anyone else does... is to "normalise" my deals. I think this is important. So that cars can be compared on level playing fields. Most other competitors have a mix of initial rental terms, hidden fees, they often hide VAT, all in the holy grail of a cheaper headline price. I do not do that. I simply make sure all my deals are comparable.
If you are in the market for a new car, I think you will share my feelings. However, if you are just doing a technical critique, you will not. I know which people I am targeting... the real customers.
Also, my cars bounce. Important, simple and fun. People love bouncy cars.
