I suppose to be objective you would need to have owned both, personally I like diesels as in general they just seem more reliable, looking at the posts in the forum the V8 would worry me at higher miles due to the cracked block/pulled liner problem (but would imagine the power would be addictive), there are a lot of starship mileage diesels as you will see in another thread but as I said I just prefer diesels. The electrics though are very dodgy, its makes my Alfa look Germanic in comparison, make sure everything works.
