Very true, interest rates are hitting market at moment. But the good cars always have a plateau, when their residual values remain high, and then eventually they start to tail off. I believe the Z was on that trend before the rate hike.
I myself timed my last move, and with a bit of luck got out of my mini just before they started a very steep slide. Held onto it as long as i felt i could before the new model started to negatively impact residuals.
My decision to bail out and let a dealer buy my car for good money has proved completely justified, as same dealer has offered my mum, who's car was indentical bar colour and a year newer, slightly less than i got for mine.
Anyways, none of us are making money playing with cars so its all really irrelevant anyways!
