Jensen Interceptor - scratch needs itching!

[JCW]

I love the look of these cars and am not bothered by the MPG but am confused by current pricing so would appreciate some advice. Personally, I prefer the Series III ideally in a bright colour with cream interior and Webasto roof and whilst the convertible commands higher prices upwards of £40k, possibly a genuine SP coming next in the pricing hierarchy, thereafter I'm confused with cars selling between £12.5k to £26k.

I would like to purchase something depreciation proof and buy something that doesn't require huge man maths to justify but am at a loss to understand the market for these vehicles...

Suggestions?

Thanks everyone for some excellent replies and information and as I'm soon back from my gardening leave hiatus and with a job offer I shall be in the market come the new year, although I may hire one for a weekend first just to make sure, rather than my usual impulse purchase.

Does anyone have experience of the models with full length Webasto roofs? Yay, nay or otherwise?

This is interesting as on one hand I have developed a taste for restoration but am far too fastidious for the good of my wallet, but on the other appreciate the finished article which has been paid for by someone else!
