Actually, I haven't gotten to drive any of them. Basically the only people that are allowed to drive them are the 3 owners and my aunt and uncle who are more than just experience BMW drivers!

I think they'd all agree that the E30 definitely has "something special" that the others don't/can't have and they ALL enjoy driving it. They can really appreciate how much of a pioneer the E30 was. Both of the E30's have been in the family for a long time (my grandfather owned the red one before my brother) so they tend to get the most love. Kind of like oldest children!
Having said that, they love every minute behind the wheel of all 3 of them! I'd be surprised if any of them leave the family any time soon, even if an E90 is added.
