Ok.
Taking on board all the great input - thanks everyone - I am starting to form an opinion of my own.
Whilst I like the Troopers size inside and don't mind the looks of the thing, it seems a safer bet to buy a Fronty. Less rot and less cash outlay for a clean one - sometimes the unfairly bad reputation of the Fronty works to our advantage!
A Monty is a reasonable suggestion but as they are re-badged troopers I fear that the rot will be the same - leaving me back looking at Frontys.
All I need to do is get some cash together and pick either a clean early 2.2DTi Series B or a stellar 2.8TDi Series A.
A Surf is not for me as I know too little about them and can't risk buying a lemon or a car which immediately needs a new head!
I'm curious to find out more about putting an LSD out of a Citation into a Fronty though...
