i drove this car with the new 3.0 v6 supercharged earlier this week and that one is quite a bit more powerful and very smooth but that one was 116k euros with some optional extras this one is 93k with about the same extras so that difference in price is hard to justify because they are not that different when you want a seriously fast xj, you can buy the new xjr or the supersport but when you don't, this 4-cylinder xj will do the job just fine
