I'd buy my current car (he says. loyally, in case it's listening...) - although all other things being equal I might be tempted to up-spec from the poverty-model black vinyl seats and rubber floors to leather and carpet. But I like the simplicity: while the CVH in basic tune on the original Weber DFT is not exactly the height of sophistication, I can maintain it adequately myself with little outside assistance; there is no electronic gadgetry to go wrong (or drain the battery when it's sitting in the garage); and while the fuel economy is nothing to write home about, it makes adequate progress without breaking the bank.
And the way I choose to drive it suits its character: to me, a 4-seater Morgan is more a grand tourer than a point-and-squirt sportscar. For sure, "pressing on" can be fun, and I'll certainly get a bit of sideways action on loose surfaces every now and again, but it's never been a track-day plaything and nor would I want one.
To me, one of the principal appeals of an older car is that it's possible to get somewhere near the performance limits without getting too far on the wrong side of the law. Narrow-section high profile tyres, idiosyncratic suspension, a less-than-hugely-powerful engine in a pretty light car, and all the other Morgan attributes add up to something that I'm not quite sure I could enjoy the same way in a new one.
