If a new 997TT is worth (£100k?) then a car which is 70% as capable in the dry and perhaps 105% in the wind and rain, how can it be overpriced. Or another way, a Golf TDI 5Dr is 20k plus.........
But..... a 997 turbo will be a £20K car pretty soon [&o]. In relative terms, of course, as it will be a few years down the line and still be a hugely risky prospect to run, but lets agree that all but a few very rare Porsches are cheap cars these days and will only go down in value.
A DB9 is now an option at £30K if you want a scruffy one. M5s, AMGs, there's plenty of places to put your money at the £20K area. Will a 944 ever be seen as so much of a classic that paying £20K is a good investment? I think not.
I'm the last person to talk 944s down, in fact I regularly get accused of being too passionate about them. But, if you want a car that's going to appreciate in value than you need to go for something very rare, and hugely desirable. Even then, with running costs any car you store has got to go up in value more than the cost of tying up the money, and the cost of re-commisioning it when you sell. You need to be looking at cars worth millions to make it worth treating them as a long-term investment.
When my car was featured in a magazine compared to an Alfa GTV6 and an Excel it was by far the best car to buy; most reliable, best to drive, good parts supply, all-round best choice by a very wide margin. If you were going to lock a car away in the hope it would be worth something in the future, I'd actually choose either of the others over the 944. Rarity and desirability are things you have to attach to cars with more "passion" to them; perceived if not real. Alfas are a classic case in point. [&o]
