As one who is about to take the plunge into "new" ownership. The cost factor is on my mind. But having played with English cars/suvs (land rovers, Mgs, Rangies) I can surely state the following.
One, driving habits tend to make a difference, also aftermarket mods (some work great while others add stress not foreseen by engineering) . But I believe the biggest factor is proper maintenance.. Following recommended intervals is a good starting point, regular oil changes is also a good insurance. Its mechanical, it is designed and will work within specs, as for the design flaws those can be rectified and once corrected will work as intended. What worries me are after market modes stressing that marginal tranny.. and the fact that (please correct me if I am wrong on this) this tranny does not need any servicing (yikes) .
The issue I believe is that this car is difficult to work on, due to lack of space and perhaps gets neglected because it is too difficult to do...circular, but logical
