I was thinking of buying a used 1999 C70 -- and I'm told the car has no spare tire so I'll need to buy one. Is the spare tire a full size or a mini?

The car isn't in front of me...hence this post...

Thanks for any help!

Some one has sold you a crock of _________! Your c-70 has a spare under the trunk floor. It is a compact one. The frame jack and "tools" are also in the same place. If the vehicle that you are contemplating buying does not have the jack, spare tyre, and tools, then I would make the seller replace all of those rather expensive items. If you call your local Volvo dealer and ask him the cost of those several items, you will be floored at the cost!
