IMHO Discovery 1, later model years.
D2 is different, in about 620 ways, more electronics, many versions of D2 lack the CDL. D1 has bigger parts in some areas. see
A Side by Side Look at Discovery I & II - Land Rover Forums - Land Rover Enthusiast Forum for a comparison. Our tech area has "what to look for when buying a Discovery".
