strip ed30 back to std and sell bits, simple economics (but obv harder on things like LSD) imho
from what little I know of you john its the journey not the end point and something 'different'
like the idea of R32/6 , and in fact done right you may end up with a modified car worth more than its original value.
TTRS is amazing and the potential
, but would you 'finish' it too quickly?
does it have to be 2 or 4 doors?
other consideration is just go straight to a caterham/noble/gt3 fully prepped track car.
keep ed30 and get a litre motorbike?
