suggest you do a search of the P38 forum...there are quite a few posts and threads discussiing the pros and cons of pre and post 1999 models ...known as the Thor upgrade.
Prior to the 1999 upgrade the engine was fitted with a Lucas EFI and an operating systems known as GEMS, 2 wheel traction control, etc.
The upgraded P38a with VIN numbers post XA410482 came with upgraded diffs (4-pin front), 4 wheel traction control, improved brake modulator unit, Bosch motronic Ver 5.2.1 EFI accompanied with redesigned inlet manifold, and an upgraded ZF4HP24 auto transmission and a few other things.
These are regarded as generally more reliable but are a tad more difficult to work on for routine maintenance....not complex, just physically more stuff to move etc when you want to play on the top end.
you can get parts readily locally and from the UK at a significant discount, even allowing for air freight.
I priced some 2003 Camry V6 parts recently for a cousin and the equivalent RR parts were significantly (30-40%) cheaper...
That aside, IMHO some of the Japanese design on the toyota engines borders on genius for its layout and quality...
The V8s imported in RR 1992-2002 were largely the low compression versions, so they are under stressed for their capacity. There is some leeway with the GEMS engine for retuning/improvement but the Thor engine mapping is highly proprietary and for all intents and purposes is impossible to remap unless you have access to really sophisticated engineering resources (Motronic 5.2 Reprogramming)
Do your research...check also RANGEROVERS.NET HOME and look at the section on common problems and fixes for the P38 then make up your mind.
The P38 design is essentially 20 yrs old...and it's British!
. You don't buy one expecting 10 yrs trouble free motoring. You need to understand what you're doing and be prepared to put the time in...it's a lot of fun!
