Hi all,
Time has come to finally change my Porsche 996 for a Range Rover, have test driven FFRR and Sport pro's and con's for both so still undecided.
Anyway my question is reliability have heard many people say they are bad, i'd guess the engines are good both 4.2sc in the sport and 4.4 in the FFRR so what about drive train and electrics?

Need to run as everyday car so like the idea of a converted L.P.G. any thoughts?

Done a search but not a lot of info.

Shop around. Gearboxes are a weakness on early cars. Once they reach 100k+ miles, they can start getting some serious issues unless they have had relatively frequent oil changes (every Inspection II is sufficient). Either buy a low mileage car or buy a higher mileage one with a price that reflects a gearbox replacement or evidence of gearbox oil changes.

For LPG, you need to do quite a lot of miles to make it pay. However, if you do you will achieve 16-17mpg equating to 30ish mpg on petrol. The BMW 4.4V8 is one of the best engines to convert as it has hardened valves and will run on LPG without any extra lubrication. The 4.2 will need Flashlube and there are some electronic issues with the conversion (speak to JE Engineering on that subject).

Otherwise, they're generally pretty reasonable cars. Most should have had the faulty front differential replaced by now (if not, Land Rover will do it free) and the electrics are mostly BMW (it's a big X5) so generally they're ok. If the battery starts going, it'll play some funny tricks but otherwise they don't have many issues.

If anything does go, it tends to be expensive. Radiators fail after six years or so (£4-500 fitted) and the alternators are water-ccoled monsters which aren't cheap either. Don't forget it's a £70k car with £70k car bills, even if you pay £15k.

The downside is you start to think that 60p/litre is expensive. laugh

Thanks Guys,

Looks like i'll be sticking to the Bmw 4.4 engined RR, hoping to get one already converted to LPG.

Have to do a little homework on the different systems, ones to avoid, faults if there are any e.t.c.
Will put my car up for sale/swap on classifieds next week.
