What are the differences between the sport and non sport models?
which do you prefer and why?

 

i perfer the sport because of the lack of chrome and rear spoiler. however the chrome does look good on some colors. some non sport come with rear spoiler and you can get a front one from Mina or Arden to make it look like a sport model. I myself have never seen 2 Xtypes look identical they made small unnoticed changes every year that are hard to notice unless you are very familiar with that model

 

As per gragner for me too
I had the Sport and much preferred the de-chromed look, but if you're a chrome fan the Se is the way to go

 

The sport seats also seem to have better bolstering and the suspension is firmer/slightly lower from what I have read. I would do the Sport again, but I may add the bumper chrome later.

 

Sport adds:

Larger side bolsters on the front buckets
18" 40 series wheels and tires
slightly lowered
stiffer suspension
no chrome, paint matched bumper strips and grill and thingy on the back that says Jaguar.
All have traction control
