We are on disco no. three. They are hard to beat as family vehicle that will also tow a big stock box and that also has a big load space. Double cab pick ups seem to be all the rage around here, but you can't fit three kids in them, particularly not on a long trip.
Yes, they have their faults, but so does any type of vehicle. Forewarned is forearmed. The first of ours, the engine died at 170K, the second, the head went at 160K, but had the block skimmed and managed to get a good trade in on it as it essentially had a new engine and the current one, we have had trouble with the suspension, but if yours is a P reg, it won't have the air suspension, so no worries on that score.
Don't rely on them being watertight - every one we have had has leaked.
