Yep the Land Cruiser doesn't ride well.

Rather than the Phaeton I'd look at the Skoda Superb. You'll get more car for your money.

As for large comfy SUVs in your price bracket, the Nissan Murano is hard to beat, reliable, loads of kit and road biased in terms of suspention.

For comfort at that price, I buy a Jag XJ or an oil-suspended Citroën C5 - however the former has quite a low seating position (not great for bad backs) and the latter may not have badge appeal.

Hailing partly from Co Clare i can understand the OP's question, some seriously bad roads down that way, and Toyota Landcruisers are a common sight, though usually the slightly smaller Colorado, probably the best bet and getting rare now due to the number being exported to Africa...no fools where vehicles are concerned.

Unlike some above i found Amazons to be very comfortable, will take any surface and iron it out, though in the budget mentioned you will struggle to find a 100 series, unless a V8 petrol not yet converted to LPG, an oil well emptying prospect, which is no bad thing if you can find a lowish mileage 80 series, as its the toughest most durable model they brought here, later shape 105's (100 series body) were not officially imported, being live front axled and steel sprung, they are the choice of the UN etc where it simply must not break.

100 series on air suspension does not have a live front axle, and is a very smooth riding vehicle, it does suffer with suspension sensor problems, not cheap, but stripping them, cleaning and waterproofing them will extend their life considerably.

I wouldn't dismiss a Landcruiser or similar out of hand, having suffered the simply dreadful ride of a hired Focus on our last visit to Eire, never again, what anyone sees in that overrated car is a mystery to me, the constant pounding of the concrete suspension left us quite drained.

The best ride of more normal vehicles, Berlingo (worth trying) and same suspensioned Picasso's are very comfortable indeed, new shape Berlingos do not have the electric handbrake as fitted to C4 pic.

Large Volvos renowned for seating too.
