ClassicV8 Schooling Needed

[Benengo]

I've always loved the look of these beast but browsing through the classifieds there seems to be quite a variation in price. Mid 20s all the way to +120k!

Is this down to Saloon/Volante/Vantage Series delta? Which tend to be the more sought after? Can anyone tell me a bit more about them?

Is there such a thing as a decent entry level V8 or would that be a longer term money pit? Any good examples you can suggest?

Apologies for all the newby questions but I appreciate any advice!
