If you have 10K and can be bothered the Cossie way is a good one to follow. Buy a crap example and spend the rest of the money re-building it to former glory.
A mate of mine has just done this with an old RS1600i, car cost 1K, spent 5K on it and it is now absolutely stunning! Plus he has an affinity with the car cos he "made" it look as good as it does (which strangely enough is fairly standard, just fecking clean at the same time)
Arent the intergrales all 4wd? If not they are a hardwork buy, dodgy electrics and complicated repairs (parts are hard)
The Porches are a good idea but, well, a bit lifeless for an old car, they have no specific cult following, (as with your Cossies or Lancias etc) Though each to their own. Have you seen the interior of an old 911, think Beetle without the class and your nearly there
