Loz,
Thanks for taking an interest from the enthusiast community! I'll try and keep it as simple as possible:
1. Reliability - the biggie. As a past owner of a 2002 Disco II and current owner of a 2004 Disco II, I must say I have been seriously disapointed with the problems I have encountered from 2 brand new vehicles. Combined, since the purchase of my 2002, I have been to the dealer over 20 times for warranty related issues!
The short list would include:
R/R ABS lights x4
Replace ABS sensors x3
Replace front drive shaft x2
leaking windshield x1
power windows (clips that break not allowing window to go up) x3
R/R leaking valve cover gaskets x2
R/R leaking head gaskets x2
Replaced rear diffrential x1
Replace noisy catalytic converter x1
Replace Throttle body x1
Replace motor mounts x5
I know there is more.....
As I type this list I think of how ridiculous it is. Our company has purchased brand new chevy trucks that go 100,000 with as little as regular maintenance and maybe a new battery.
2. Defender - bring it back, in some shape or form.
As far as offroading is concerned, you (Landrover) pretty much had it figured out (pre 2004). Yes, things can be improved, made better, etc. but as a whole all of the products were and are capable in their stock form.
Address item number 1 and bring it back as item number 2. (and don't market the thing against the Hummer)
