They are worlds apart from the P38 in terms of driving - they are more planted and car like....as GDM says, they are an X5 with a posh frock.
But they are still riddled with infamous Land Rover 'failings' and the M62's passion for PCV valve, Timing Chain Guides and VANOS issues.
They are more reliable than the P38, (just) but the repair bills and vehicle complexity can be exponentially higher.....but the driving rewards are greater.
I am one of Range Rovers biggest fans, and have owned many over the years.....would I swap my L322 for a P38 - No..... Would I have a P38 and an L322 - if I had the room hell yes....
Gearbox is the main issue on the L322 - all other things are just niggles and annoyances....but the ZF5 gearbox (the Torque Converter particularly) is the big stumbling block on the V8 2002-2005 L322's
The engine is strong and powerful, she is fast and pulls like a train.....much like all M62TUB44 powered vehicles (the E38 740's and the E39 540's) it is a long standing and time tested engine....all the faults are known and well documented on forums and other internet resources.
Parts are getting easier to find, but shop around as prices can be eye watering!
A Range Rover with a fault can drain ahealthy bank balance rapidly if you can't diagnose and do your own repairs.....The early L322's are complex, but are still home DIY'able if you can read a manual, use a computer, figure out the wiring diagrams and can tell the difference between a spanner and a screwdriver.
They are awesome vehicles and once driven forever smitten....pity Vauxhall nabbed that catch phrase......drive one and you'll fall in love.....but keep both eyes open.
EAS is not a major issue, main problems are well documented chiefly compressor wear and split air bladders....valve blocks can be an issue but not as much as the P38 so it seems.
They hate weak batteries and can throw a right wobbler if they even drop 0.1v to low!
Most common issues are battery drain - chiefly the FInal Stage Resistor - not a difficult or expensive job, just access to it can be a pain for the 'larger' fellow!
DO plenty of research and don't go for the first one you see....ask plenty of questions and seek counsel on here....never take a sellers word for anything, they just want the contents of your wallet!
I love mine - as I did my P38's.....you just have to understand they are a Range Rover and they are born to be Divas!
