Your 1:1 Fiat presumably has a slightly smaller engine. I couldn't believe how big the motor in this one was when I opened the box.
Thanks for the tip about the rear springs. I still have time to correct the error you highlighted.
Another thing, given the care taken with the rest of the model, I was surprised at how short the screws on the springs are. I was thinking I probably need to use rod but may be cyano will be strong enough.
I did finally manage to get some paint on it at the weekend. I'll post some pictures when I get a chance (though it's only likely to be springs!!!!). You were right about binding the springs being a faff. Painted they are beginning to look quite good, though I am not sure I have captured the actual colours.
I am not planning on going mad with detail but there are one or two things I want to fix.
I am not sure that I can live with the screw heads. Filling them might be even more of a pain than the springs. The model shop suggested stretched biro. Hopefully, it won't come to that.
The other bit, at the moment, is that the planks on the firewall need to be up and down not side to side! But let's deal with that another day.
