as chip has said-go for it
i know lots about the car as i really want one. I know James Waddington failry well of that Lotus site. To get the engine done he had to have some parts especially made as you cannot get them.
If i remember rightly it costs around £85 quid to fill the tanks. Its gone after around 230 miles 'ish or therabaouts
The brakes are £380 each corner or were around 3 years ago.
Still would not put me off buying one. ( i will get one eventually, its my personal goal) They will be a future classic collectors car. Only 1040 were built or so.
377bhp twin turbo 3.6 motor for around £15k>cheap as chips
Go for it mate
