Agreed Frog. But I don't think the standard GTi is a particularly "flash, ostentatios" car. It's not as if it's covered in massive spoilers and lurid paint jobs. It is, however, obvious what it is to scroats, thus the need to be careful about where you leave it.
Indeed, I actually changed my mind from a red one to the grey one because I thought it might be a bit less "obvious" so I do understand where you're coming from Mr Grenouille.
