grim reading but as you say, realistic. The best place for your money in a car right now is a ferrari 355, they about the only car not suffering from plummeting prices. Buy a good one for about £38k and you'll not lose a lot at all. Buy a german mass made car and you'll haemhorage money like theres no tomorrow................
I understand your figures in todays market but I think you're missing my point, this massive drop in price has already happened so you're starting from a lower base point and if there is (big if) a pick up in the economy over the next two years maybe with the huge drop todate prices may start getting back to something like they were 12 months ago,i.e a two year old zed was worth £20k 12 months ago.
Never gonna happen. I can understand your thinking though. i bought my UY zed for £25k when it was 5 weeks old, the original owner paid £32k so he took the initial £7k depreciation hit. i ran it for a year did 20k in it and still sold it for £25k. That was obviously in much better economic market conditions.
I don't see the point in buying a car inbetween your current car and the 370z. your gonna take the hit on sale of your current zed, will pay extra towards the new zed, will lose on sale of that and then will have to add money to purchase the 370z
