People who know something about cars might appreciate it depending on which Ferrari I got, people who get jealous easily might think I was a cock, people who are against pollution might like me more than the guy driving the Audi behind me, people who are against spending too much money will be busy complaining about people who own private jets. So I guess it depends.
Though to be honest, I couldn't care what any of them thought.
I'm sure they would value your opinion equally.
