Which one Del? The facelifted L322, from '55' onwards? TD6, 4.2 SC, 4.4 or 3.6 TDV8?
They are still plagued with air suspension issueslike the Classic and P38. I bought my '55' plate TD6, and literally 10 minutes later the air suspension went wrong, went to 'extended mode' which is the highest possible, adove the highest you can set from the cabin...I then had to drive it back to Oxford from Brighouse...took the RA's slowly

If you get a TD6 check if the splines have been done, mine went to my local dealer FOC for some work to be done because of a manufacturing fault with a few TD6's. But if left, there will be a very expensive bill looming. I paid for mine to have a £400 service, which wasn't a full service...just a routine quick one...so budget for that.
There's a few oddities with them, like condensation in the rear lights...but that's normal

It was a good vehicle, but sell it asap...prices can drop from one month to the next, buy it dirt cheap one month...and two months later you could struggle to sell it.
