My list in this gold-plated daydream usually includes a Bentley Continental GT, a Ferrari or three, something lavishly bespoke by Bristol and a humongous stretch Cadillac, complete with chauffeur and bar overflowing with Kristal champagne.
Anyway, you get the idea. Well, the thing is, I managed it for real - for a couple of days at least - cossetted behind the wheel of one of those Lottery dream cars, a Porsche 911 Carrera 4 Cabriolet, no less. The occasion was the Press launch only a few days ago in Germany to put the latest version of Porsche's new 911 thoroughbred through its paces. The venue was the very grand Hotel Schloss Bensberg, in Bergisch Gladbach, near Cologne, the sort of place for any self-respecting Lottery winner to take his ease.
But the Press pack was busy, squeezing themselves into a variety of 325 and 355 horse-power versions and, with power hoods glidingly folded away, taking to the unrestricted autobahns to let loose these supercars in their natural environment.
It was my first taste of Porsche power, and now, days later, I still feel pretty awe-struck.
It's not just the breathtaking acceleration and heart-quickening high speeds, but the overall feeling of a car that is so very much "together" in the best sense of the word a true mechanical masterpiece.
This sense of completeness was aided by the legendary handling, taken to an extra dimension by four-wheel drive, denoted by the 4 in the model name. The system adds extra grip to an all ready griptastic machine. This engineering perfection seems to extend to every element of the car - the automatic soft-top folds away in just seconds, even while driving, at up to 30mph, a provision no doubt, spurred by the vagaries of the British weather, for the UK is Porsche's third largest market.
I tested both six-speed manual and Tiptronic S five-speed automatic transmissions and fell for the latter, which offers slick and effortless auto-shifts or more involving semi-automatic selection by steering wheel-mounted switch.
The car is a true attention-seeker, and the squat, powerfully-haunched look is enhanced in the four-wheel-drive cabriolet, which is one and three-quarter inches wider at the rear than its two-wheel drive counterpart - ample space for those funky, extra-wide, low-profile tyres.
The new model maintains the classic 911 look, while the inside story is one of a car for the new millennium, boasting figure-hugging, power-adjustable sports seats, with everything that can be - including dashboard and door facings - trimmed in tasteful, dark leather.
Drawbacks? Well, you won't be taking your family of five on days out or lugging flat-pack furniture from Ikea. But, then again, you wouldn't expect to.
