If the engine on your Puma gave up and needed replacing?
My answer would be..
As long as everything else is in good working order I would keep the car and look for an alternative engine.
I would start with looking for a well serviced 1.7 out of a rear ended write-off.
If I didn't find a satisfactory example then I think I would convert the car into a 1.6 (with the above qualities) as this is less likely to give up in the long run due to the steel liners.
