The classic was, like all earlier landrovers, built to be fixed. The P38 was a transition to a time of more integrated electronics and parts designed to be replaced rather than fixed (wheel bearings etc).
Unfortunately the P38 was too early for standardised electronics. Longer term it appears to be the loser in the collectable and usable stakes. The classic is the classic and can be fixed easily for minimal cost with lots of interchange with disco and defender. Where the P38 can't and has a lot of proprietory parts.
If I couldn't have my classics, I'd have an early td6 L322 and try to fit a 6sp manual gearbox.
