Yep, they are excellent daily drivers. I think its my sixth 911 (although four of those were between 1976 and 1983) and all have been daily drivers, I've done around thirty thousand miles in this one in the last few years. Took it up to Millbrook Proving Ground last week and drove the absolute nuts off it and it was bloody epic.
I've spent more than a few quid on the car, but in fact that was more for my OCD requirements than what was strictly necessary. But it is totally sorted now, Wayne remap, chassis legs, new sills, new wings, repaint, reupholstered Big Reds, Ohlins coilovers, Lightweight Flywheel, Goldenrod, RS Gearshift, MPL clutch slave, massive anti-roll bar and chunky strut brace, and some trick unobtainium steering parts. etc etc.
In normal driving mode there is not a rattle or squeak from any part of the car (although weirdly the doors did sound as if they were coming off on the Millbrook Handling Circuit).
Its not a particularly quick car in this day and age, but for an old git like me, its perfect, you can give it full beans all the time and get all the fun without going at the warp speeds a modern 911 disappears down the road (although I have a couple of motorcycles for that sort of lunacy!)
It handles beautifully, initially understeering mildly at the limit controlled easily by the throttle into mild controlled oversteer, nothing like the snap oversteer of the older cars, although that can be induced by being really heavy handed.
Every journey is an event, I see other people in their expensive washing machines and wonder if they know what they are missing.
I'll never sell mine.
I'm a firm believer in using them regularly otherwise they just dry up . .
