As Hurnleft says, the panels are great value and it's just a bit of final fettling that's needed to get the panel gaps right.
These cars at Stoneleigh last year all looked fine, even though they weren't in paint the panels fitted pretty well.
Instead of thinking along the lines of paying someone to fit the panels, how about relishing the challenge and having a go yourself?
The finished result will be something you can be proud of, even if it isn't perfect.
