400 sport or older V8?

[MellowshipSlinky]

I'd set myself to buy a lightly used 400 for <£68k, but have since realised they've got a fair way to fall in price if they're already being discounted.
Lovely car though.

Now thinking a 3 year old V8r may be a better option - mid 50's gets a lightly used, albeit pre facelift, high spec car with 2 years warranty, and I'm hoping that most of its depreciation has been done...

Found a few with between 6 and 18k miles at 3 years old.
The higher mileage one has a better spec (for me) but what mileage is too high come resale?
We'd be using it, so would chuck on another 20k over the next two years.

Are these cars reliable at this age/ mileage?

I'm a newbie to Jaguar, coming from Porsche/ Lotus (just sold my Exige 350) so could do with some owners input

Tried a V8 Vantage, but didn't really do it for me.

Cheers

Got a drive booked in one on Saturday.

If I like it, I'll buy it but it's only the 2wd version.
As the wife will also be driving it regularly would the 4wd be a safer bet?
