Often you’ll hear derogatory opinions about Jags from people who have never owned one, or don’t know how to care for one, or cannot afford to pay someone else to care for one.
As far as X300s go, well, as good as they are, by now they’re all getting to the point where age and miles can start taking a toll…like any other 25 year old car. If you have the ability, desire, means, and patience to deal with a 25 year old car (Jag, Buick, Honda, whatever) then you can have a great daily driver.
If not, you won’t.
I’ve had Jags as daily drivers since 1997. Great choice for me; I love 'em. Not the right choice for everyone, though.
