Um no, stick with your M3. The M3 is a great car and packs alot of punch in stock trim.

Sure, Tiburons "can" be fast, but so can any other car for that matter, with the right amount of money.

You have the best of both worlds (performance and style), not to mention rock solid reliability. Anybody who tells you M3's aren't reliable, either don't know what the hell they are talking about, or actually owned an M3 and never properly maintained it.
