Hi,
I have just bought in Japan today a 104,000 km 3.0 Harrier, 4WD car cost was 580,000 yen so around £2700 and cost back here around £4500 OTR, as its just over 10 years old its SVA exempt and as its older than 2001 the engine size doesn't really matter tax wise. This one does not have leather but not worried about that, was more concerned about genuine k's and service history.
My brother has a 51 plate RX 300 and other than no leather its as good a spec as his. My guy in Japan said not to go for the 2.2 as although its OK the 3.0 as already stated is a lot better also I am going to tow a caravan so wanted bigger engine.
One word of advice is dont't buy from UK import auctions or of a dealer who has because all the ones sold from the UK auctions are all the CxxP in Japan they can't sell and bought cheap for resale in the UK auctions, if you want details of an agent let me know.
David.
