I recently sold my 2003 Z4, purchased new in August, 2003.
It had 52,000 nearly trouble free miles.
It was never driven hard and always garaged.
I was 52 with good knees when I bought it.
Ten years later my wife and I have both had knee operations and getting in and out was a chore.
Plus, at 6'3", getting in and out with the top up was a chore.
With a wife who doesn't know how to pack lightly, anything more than an overnight trip wasn't practical due to the small trunk.
Plus no back seat meant no rides for the dog or grandkids.
So, it's gone and a new 128i convertible is on a big boat between Germany and the US with delivery expected soon.
I hope I have as much fun with this one.
Handling and performance.
Just be prepared for a small car with little extra room.
