Harbour Cars - Suppliers of the finest used Porsche & Mercedes-Benz need the ultimate logo.

Harbour Cars

We sell used Porsche cars primarily and also Mercedes-Benz and other luxury high performance cars. We have a showroom and sell to the general public. The vast majority of our customers are in the UK but the website does get some international business.

I'd like to explore the following colors:

Blues: Knowledge, trust, calm and honesty.
Light neutrals: Purity, balance and sophistication.
Let designers make suggestions:

We have been established 16 years so are reasonably well known in our specialist area of the car market. People know our logo but we are ready to change it.

Our current logo has .com included which is no longer necessary. It also has a a fairly 'safe' corporate swoosh curve that is actually now so used in business its a bit naff?

IDEAS:
One thought we had though was to play on the name and that we are geographically by the coast & harbour and perhaps adapt the curve into a wave influenced shape and/or play on the fact that a Harbour is a safe haven from the ocean rather like we are as a business......this is just a thought and we are open to other suggestions perhaps even without any supporting shape.

COLOURS:
At present our colours are Silver/Grey/Blue in an effort to exude quality and luxury but perhaps a purple-blue with silver is a thought?

Either way it needs to work in black and white as well.

WHERE IT WILL BE USED:
The logo needs to fit on all the usual places like business cards, letterhead and website but it also needs to go on the side of our showroom, van, on glass, keyrings and in particular on the inside of the rear screen of a car as a 'cut out' logo so that it doesn't just get printed onto a sticker but looks nice cut out on its own stuck in the rear screen.

Thanks for your help and effort.
