After a long hiatus, I am back on Oppositelock...thanks DasWauto!

My awesome girlfriend gave me the go ahead to start searching for an E30 and my heart is set on a 325i. 2 door coupe, sun roof, lsd, basketweaves, and very few performance Mods, at most suspension, and chip. Im willing to wait 1.5 years before i find the perfect one at the right price. it will be a second car, so that brings me to my next question. I know I don't want a vert, but they look awesome!

What would the difference be between a 2-door and vert on insurance costs? I'm a upper 20s male with no at fault accidents and no claims.
