I'm actually considering buying one as a work SUV.
From what I've seen on the JLR groups and forums, the V8 HSE petrol seems like the better option over the diesel V6 option. Apparently turbos have failed even on low mileages with them.
Of course the V8 will definitely have the higher fuel bill, but at the same time I rather have a higher fuel bill than maintenance bill. Think V8 is my preference. There are a few on the market in the mid R200k price range.
Sorry to break this to you bud, but the rest of the car is still pretty.... err crap
Had a Disco V8 HSE - amazing car and went with the V8 because of reliability. However, everything else, from the suspension, to the gearbox to the random electronic glitches forced me get rid of it. A new warning light every second day... Engine gave no issues though, but flippen thirsty!
Moved to the Disco 4 SDV6 HSE but newer and under warranty (at the time). Had some issues, but sorted under warranty.
Honestly, some of the best family cars I owned in terms of comfort and practicality.
Just wouldn't touch them without a warranty, which none of the Disco 4's now have.
