Uniques are solid, well built cars with beautiful, accurate body lines and a correct stance. They have an excellent support network from the manufacturers. If you do buy the car, you can contact the Weavers at Unique Motorcars and they will be as helpful and welcoming as if you had just bought a new car directly from them.
There is also a dedicated owners forum with a wealth of support and expertise:

Older Uniques came standard with an MGB steering and front suspension system. There was an optional upgrade to an in-house fully adjustable coil over front suspension system which I believe is now standard equipment. When I bought my car it had the MGB setup and I easily swapped it out for the complete, bolt-in upgraded coilover system. Both use an MGB steering rack, so you should verify which setup this particular car is equipped with. Either way, if the price is right and the car was properly put together and maintained, it is well worth serious consideration.
