My opinion would be that you should buy the car you want. I've had a 3.6 and 4.4 TDV8, both facelift, I like them. Also had a 2008 3.6 TDV8, they're all brilliant in their own way. at 205k I would imagine a lot of the things that would need addressing may well have already been done.
You've got a healthy maintenance pot so I'd say "go for it". Enjoy.
