V70 vs. V50

[TeaNoSugar]

Hello, just after some help with the two volvo estate models. I have a budget of around £5.5-£6.5k to get a car. I get a car allowance from work so anything >9-10 years old will be taking the piss and ideally I'm looking at 2009 or later

I've narrowed it down to:

Volvo V70 2.4 D5 (2007-2010)
Volvo V50 2.4 D5 (2007-2008)


I really don't know which to choose, the V50 seems to work out the cheapest, and to be honest I don't really need the size of the V70, but I really like the idea of the comfortable seats/ride, the space inside the car, the decent standard levels of kit, and the long-lasting, tough, reliable reputation the V70 has. I can't tell from my research if the V50 has any or all of these features. There seem to be dozens of V70s with 120k-200k miles on them, which makes me more inclined to go for a higher mileage car.

I'm going to look at one and drive it today; a 2009 Volvo V70 2.4 D5 SE (Premium Pack) Geartronic 5dr

Also, does anyone know much about the trim/spec levels? There seems to be 4 or 5 but I can't tell much difference between them.

Finally, is the built-in sat-nav any good? And is a full volvo service history much of a bonus point?
