If I had worn a hat, it would have been perfect. We're kicking off our PH 'Open Season' with Porsche's simplest offering and, after an (icy) afternoon blast around some of Surrey's quieter roads, an object lesson in how to make a damn fine sports car. And a reminder of how cold a fellow's head can get.
The current iteration of the Boxster has been around more or less unchanged (barring a mild refresh in 2009) for half a decade or so now, and it remains a shining example of how Porsche can sometimes get a car so bang on straight out of the box.
Everything it does just feels absolutely right, from the ideally balanced, weighted and positioned pedals, to the just-so gearbox, to steering that responds quickly but without seeming hyperactive.
But we all know that the Boxster is a fine car to drive; what really counts for the purposes of 'Open Season' is whether it's a decent soft-top. And you have to say that here the Boxster scores pretty highly.
One of the key benefits of open motoring is that you can hear engine notes that much better. Of course, this only works if said engine sounds good in the first place, but that's all right, because the Boxster does sound rather lovely.
The 2.9-litre flat six (this is hair-shirt Porsche - no posh 3.4-litre 'S' model here) is nothing spectacular in the power stakes - 255bhp and 214lb ft won't set your trousers on fire - but from around 4000rpm all the way to beyond 7000rpm the sceramy, creamy gurgle that emanates from the (optional sports) exhaust is genuinely intoxicating.
It's also quick enough to keep you interested, particularly if you're feeling sufficiently brave to switch off the Porsche Stability Management system. Our car also had the optional limited-slip diff fitted, which is a seriously worthwhile addition - you can really feel it doing its stuff as you accelerate out of slow corners.
If we have to pick a fault, the general view among the rest of the chaps in the office is that the heating doesn't win the battle convincingly enough against the worst excesses of the current cold snap.
But then engine isn't in the most appropriate place to warm the driver at high speeds. And compared with the personal 'Open Season' I endured at the tail-end of last winter in my unheated PH Fleet Caterham Seven, the Boxster's cabin might as well be heated by a blast furnace - so these things are all relative.
As fresh-air motoring experiences go overall, however, the Boxster is near-unimpeachable. It truly is a fine - and very PH - way to start our season of wintry open-top motoring. Now if you'll excuse me I have a bobble hat to buy...
