Excellent choice!! I picked an NB 1.6 and honestly, it's probably the most fun car I’ve owned! As it's being used to do track days and generally just to mess about with you can just enjoy them for what they are.
So far I’ve done croft, Three Sisters and Oulton Park, also taking it on a Nurburgring trip next year all being well.
It’s currently got the below fitted:
Ebay coilovers
GCF1 Roll Bar (Highly recommend)
Braided Brake Lines
Momo Wheel
Front and rear strut braces
Uprated pads and disc
Clean up of the underside
MG/Rover alloy wheels painted white
Few daft stickers (gotta be done)
I've only yesterday purchased a second-hand cobra clubman bucket seat and a 4 point racing harness which I hope to fit at the weekend. They are great cars and I plan to run this until it becomes a really uneconomical repair, just fantastic with the roof off.
