Got the trophy for going 400km/h last night in my Puegot 908 HDi FAP. Car is easily my favorite so far.
I have an extra one, bone stock, no miles if anyone wants one and would like to trade for it.
Also, I realized that you get a horn for every 10 cars in your garage (10, 20, 30, etc), and a rare paint for every 30 cars in your garage (30, 60, 90, etc.).
If you are nearing a multiple of 30, keep in mind that when you are given your rare paint, if you don't like the color, you can exit the game after you get the paint and before the game saves, so you can try again at getting a different paint. I want all these matte paints but don't want to waste them! If I get a 2nd Silver Chrome I'm definitely painting something chrome.
