Here's my two penneth:-
Price of vehicle is irrelevant to me - it's your money - only you can make that decision
. Notwithstanding that, I'd suggest that a 90 needs to be a long term purchase to make sense at all.
Be very aware of the proper maintenance requirements of a 90 - you'll need tools, and the wherewithal to do the work your self to a high standard - or you'll need a money tree. IME, garages do NOT maintain vehicles - they might, if you are lucky service it to a basic standard.....
Security wise - get a tracker. There's a thread on here about how to do it very well....
As a daily, a 90 might suit you, it might not - it will NOT suit me - I'm far too tall, with long legs (36" inside ), so I don't fit.
Forget how shiny it is - it's irrelevant to the main issues with LR ownership - the mechanicals and structure - granted this has a galv chassis - what about the BH ? What are the brake and clutch fluid like ? etc .....
IMHO, this age is the right age - it's pre SVA and pre electronics, so easily fixed when it breaks.
