OHHHHH NOOOOOOO....keep the E28!
There’s a support group for you... www.mye28.com
This site is dedicated to E28 owners and everyone helps you out too with any questions you come across.
There are plenty of upgrades you can still do for your car.
Here's where I was at the end of last month...http://www.maxbimmer.com/forums/showthread.php?t=72799
You'll see that there are all types of upgrades that are available, so keep that oldie going.
And if you want to see more, come out to TedFest on July 22, 2006 from 9:30am to 3pm at Parkview BMW...1155 Leslie street, Toronto, Ontario, M3C-2J6. You'll see the crew that went down to 5erFest (E12 and E28 show) and some others that couldn't make it.
