Car appreciation... the aesthetics, the engineering, etc

My 190E has been showing signs of dying for the last couple of years but I've not been able to spend a lot on it to fix it properly.

It scraped through the previous MOT with a number of advisories, but this time it's failed spectacularly (as pretty much expected).

The issues being:

• Serious exhaust leak
  
• Ball joints need replacing
  
• New tyre needed
  
• Windscreen wiper motor broken
  
  

There a few advisories too which would cost a bit - brake pads, etc.

So basically:

• Does anyone want a knackered but potential "future classic" for a low price?
  
• If not, what's the most cost-effective way of scrapping a car?
  
• What could I get for c£1k that could be reliable and better for carrying a baby? (And ideally a bike as well)
