Purchased a used Dinan 5, 540ia supercharged. I had owned a 1985 735ia before. Interior was very close to the 735. Power and handling was vastly better. 0-60 in under 5 sec and 60-0 makes your stomach turn. Corners are FUN. 90 degree corner at 60 kph and no problem staying in my lane and No tire squeal. Wow, I have driven many sports cars, but this defines sport.
