1999 C70 convertible convert newbie

I am looking at a 99 C70 convert. The body of the car is in great shape and the leather shows a little wear. The last owner destroyed the engine and they only want 975 dollars for the whole car. If I can find an engine at a decent price would this be a good car to purchase? How hard is it to take the engine out of the car and replace it? I found a 99 2.3T v70 engine.

I am pretty mechanically inclined just wondering the time involved. It doesn't look all that difficult

Thanks
