Well this one is a bit tough IMO.
I of course have a ridiculous and fanatical love for the E30, but I'm not certain it is the best choice for your wife and the purpose of the car.
The M20 is a nuclear bomb proof motor... If you have it sorted and keep an eye on things. For example, that one you are looking at will need a good bit of stuff just to make sure it is safe for your wife:
- T belt, tensioner, water pump
- T stat housing
- I'd guess brakes
- fan clutch
- I'd bet the suspension is bordering dangerously worn out (lack of control)
- I'd also bet the rack is leaking and/or wasted
That's just off the top of my head and- admittedly due to my psychosis- I could find another grand of stuff to do in about a 30 second look at the car.
I hate to be a traitor, but you might be better served to find a Corolla or the like as a commuter. That is unless you truly want another project to work on. My only real fear is that you'd spend more time fixing one like this, than allowing her to drive it thus negating the purpose of the purchase.
