Jeff - As the proud owner of a lovely 6 year old but mint blue Jag XK8, I say go for it. Once you've dismissed depreciation, fuel cost, insurance etc. etc. and you get down to the enjoyability and affordability criteria then you've made your mind up.
I rewarded myself following 18 months of solid hard work. I felt I deserved it and fortunately so did my missus.
Je ne regret rien!

The only iffy thing for me is the colour.
