I do a lot of work in Turin and can say it's a good place to visit for a few days. Haven't ever driven there as I always fly in, but have driven within 60 miles of Turin down through France on the Toll Roads.....good journey but rather monotonous. Took about 9 hours of sensible speeds with a couple of stops.
As for Turin, some fantastic places to eat and drink (including an English pub right near the Porto Nuevo main railway station called The Huntsman....cider, ale, steak and chips), plenty of hotels for varying budgets (although many don't have parking within the city....in fact parking may be a problem), friendly atmosphere and some good sights. It's great to leave the hotel, wander down to the main square and just stop at whatever bar you feel for a drink, then move on to the next one. Even better when the weather is good.
Could well be up for this.....if we ever get the darn car!
