Scotty,
I hear what you say, but I can't really disagree more! The best way to keep equipment in good condition is to use it, and regularly. As I have said on this forum several times, my S2 used to be used about three times every two weeks, for a short journey every time. About two years ago circumstances changed and it is now used for about 12-14k miles a year, driven 40 or so miles every day, come rain or shine. It has changed from being sluggish, reluctant to start and thirsty to enthusiastic, starting on the button every time, lively and significantly less thirsty. Machinery which is not used will deteriorate, and the way around that is to start it up often, get it good and warm and drive it. (Ever heard of the phrase "Italian tune-up"?) 944's were built to be used, and used hard, and doing so will do them no harm whatsoever.
Rust is a fair point, but damp is the enemy here. Air circulating through and 'round the car will ensure everything is dry and keep the tin-worm at bay. Yes, winter road salt is an issue but as Peter has said, preventative measures are very effective.
Economy? I pay less than £500 for fully-comp insurance for my S2, aged 34, left on the streets in East London. Sure, I could pay the tax, depreciation and insurance on something modern that does 35mpg and drive it each week, but I'll bet that will work out significantly more expensive than suffering the 7mpg drop by using the S2. (Maths: Difference between 27mpg and 35mpg for 13k miles/year is £550, with fuel at £5/gallon. That £550 will rapidly disappear with the road tax (£180), MOT (£50), insurance (£350 perhaps?), etc you'd have to pay on a second car. Throw in the cost of buying it, some depreciation and a bit of maintenance and you'll be a LONG way out of pocket.)
And what's the point of owning a decent car if you don't drive it?
Oli.
