Which model xk /xkr

Good morning ladies and gentlemen , I hope you can help me I’m looking at buying a jag xk /xkr I’m not really worried about the power side of the car as I don’t rush around but I’m interested in the more desirable model as I only do approx 1200miles per year , I’ve been looking at a 2003 xkr 83000 miles and it’s beautiful but the older style , I’ve also been looking at a xk 2006 model different style but again beautiful I’m just wondering if one model is more or will be more desirable in the future . I’m looking at spending somewhere in between £8000 -£10500 ive even seen a few xk 5.0lt with 100,000 miles just very confused into which model / models are the better choice .

Any advice would be much appreciated as I’m totally in the dark about these cars , thank you in advance Chris.
