From what I've seen on this forum, the vast majority of cars are tastefully done. And by far the most common mods are those that improve power or handling. Mods that have a bit of logic behind them.
However, in other corners of the enthusiast scene, you'll always get the type of cars and the type of owners that mod for the sake of modding and end up making an abomination of the car they started with. I won't name a particular marque, but I'm sure you follow me.
For some it's more JDM tea tray spoilers and chopped springs than hybrid turbos and anti lift kits.
I've yet to see a 'bad' car on this forum. It's nice to know you're in good company.
Of course the mk5 GTI is a great all round car as it is, so keeping one bone stock and clean is just as commendable as modifying one tastefully.
