GT Models - Disassembly?

[BluesHead]

Hi Guys,
Just caught the modelling/collecting bug again after 30 odd years - interest sparked again by recent heath retirement and the love of all things Motorsport related.
Thought I'd kick off again with a 1:18 model of my current car, BMW M240i, but could only track one down from GT Spirit Models in Melbourne Red (M235i but visually the same). Thought it would be a nice starter project to respray it in Mineral Grey Metallic to match it's full size big brother but stumbled at the first hurdle...disassembly
There is 1 screw at the front of the chassis but no other obvious way to remove the chassis from the body - may be simple enough but I don't want to force or risk damaging the body at such an early stage.
Would anybody have any experience of disassembling GT Spirit Model cars or offer any relevant advice to get me started?
Many thanks in advance for any assistance.
BH.
