"Aggressive-looking bumpers" - what???? - LHM
Just browsing through this week's 'latest deals' section, I noticed Seat offering:

Leon 2.0 TDI Reference Sport with styling kit: £2,500 worth of aerodynamic styling kit ready-fitted for £16,995 RRP. Highlights include aggressive-looking bumpers, 18" BBS alloy wheels and twin chrome exhaust pipes.

"Aggressive-looking bumpers" - what the hell are they? As if there's too little testosterone-fuelled aggression on the road already.... :-(

What next - 'aggressive looking' indicators?

Shifty-looking headlamps. Hungry-looking grille. Strangely innocent and vulnerable-looking rear end. Low, mean stance. Hoarse-sounding exhaust. Pathetic, whining horn.

Does anyone know a good car psychoanalyst for my confused vehicle?

Maybe they mean something like this:

Doesn't imply any insecurity about anything. Of course not.

Sounds like a Ford Focus advert where they stated the car had "sporty front fog lights". If it's foggy I wouldn't want to be driving sporty and I wouldn't describe lights as sporty per se.
