The Stretka is great fun, and many parts aren't much different to the KA. However, I've just had a tear in the rear window, and was quoted £320 to replace just the plastic window. In the end, the Ford garage said that the rear window can be difficult to replace as it doesn't pull tight, and it ended up being a whole new hood. Not sure how much this cost as it was done through my insurance. My only advice is that repairs to the hood can be expensive, so when buying, make sure it has no faults in the hood before agreeing to anything.
