I would recommend against buying a car without viewing it. It's amazing what pictures can hide.

Good bodywork is preferable to good mechanics. It can be very expensive to repair extensive rust especially if you're unable to weld.

Be aware that a tatty car with rust around the edges often hides other surprises when you start to look under the surface. An owner that has neglected small problems may have also skipped or bodged other problems rather than fixing them properly.

I hope that this is of some use to you, and good luck Capri hunting.
