2004 NOBLE M400

This is not your normal Noble, almost every part has been developed and upgraded at a huge cost and time, approaching £200,000 has been spent on it (yes you read that right!)

I would describe it as a M400+ one friend called it a Caterham R500 with a windscreen, door and A/C.

It has power to weight ratio higher than a Mclaren F1.

The car has been flat floored and weight is 1020kg, but with fluids and fuel.

I can’t express how good this car is over a M400, it’s another level.

Let me be very clear this is not a race car, it’s road car, which will easily keep up with a GT3RS.

It starts every time, never over heats, air con keeps you cool, you can run the suspension soft on the road to soak up the terrible UK roads, or stiffen it right up.

It’s got pneumatic exhaust valves so your neighbours won’t hate you in the morning, repackable exhaust so you can actually go on track, it’s cheep to insure, cheep to service etc etc

I have put a walk round video on youtube if you search for “Mountune Noble for sale, walk round”
