Robbie, John,
Indeed... Tarka stands as the high point of the Aero Chassis and the CX can be seen as building on the strengths of the Aero and overcoming most, if not all, the weaknesses. Comparing the Trad with the CX is like comparing a late1950s car with an early 2000s one, So it isn't a surprise that the CX cars are better engineered than the Aeros.
I was positively surprised by the overall fit and finish of the 22 year car, the space in it, the doors that open fully and stay open, giving easier access than the Plus 8. The seats were excellent, but I didn't get to drive it, only an original launch edition car.
Running through the configurator came up with £75,000 so it is anything but cheap...we shall see what the cost to change will be.
Performance is not far off the Plus 8 and the BMW auto box is, from past experience, excellent. The now dated 6 speed auto in the Plus 6 is in comparison, somewhat ponderous.... I think with the new sport exhaust, which I understand is loud, it could be good, but it is never a V8.
I don't need to change, I'm not sure if I really want to change and if I wanted to I can afford to change.
We shall see...
