As the family has grown I need a 7 seater. And for some reason I'm really fancying and Disco.

TD5 or V8 on LPG?

Td5 is known for unreliability and many common faults.
The V8 seems to have a hell of a better opinion of it on the LR sites.

LPG and the Td5 will be about the same to run if not a little cheaper for the V8. Td5 does about 30mpg and the cost wise of the v8 LPG works out about 30mpg.

Anyone have any experience and/or opinions?

One bonus being I can crawl under and service it my self and parts are hugely available and cheap.

Cheers.
