It only matters if you intend on selling it in a few years otherwise low mileage and condition is the Ducks Guts.
I had this dilemma 10 years ago when I purchased our 1991 HDJ80 Turbo Diesel it was 9 years old at the time but had done only 74,000kms, all original bar the 2 Analogue phones... I paid a lot for it at the time as Book price was way way lower and for the same money I could have bought a 1997 lowish mileage Petrol LC...
But I knew what I was after and once it was in the shed there would be no need for a further upgrade... Ten years later and nearly 20years it has had many $ spent on fruit, 275,000kms now and is still going strong, I have no intentions on upgrading it as I bought wisely... Others will upgrade every 5 years so age is more important. Most when buying a 4x4 and plan to add on those extra bits like BullBars, Winch, Lift, LongRange Tank etc etc you really don't want to give them away when you sell it... Do your research well and once..
On a last note prior to buying a vehicle and ask myself two questions
1. Will it still look as good as it does today in 10 Years time?
2. Will I still like driving it in 10 Years?
Well I think the 80 looks better today than it did 10 years ago and I love driving it still….
