Graham, how do you think a TC would compare with a 4/4 ?
Completely different world.The TC is now not so much a classic as a vintage car - a great toy if you like tinkering and dont want to use it as transport, but extremely irritating and frustrating if you do. There is no comparison with a modern 4/4 whose mechanics are from a different era.
So really the answer is more about you - how you want to use the car, what you like doing in your spare time, how mechanically competent you are, whether you have a beard. A TC isnt so much a car as a hobby.
