My neighbour currently has 17 in his yard. Must have owned well over a hundred in his lifetime. Many in poor condition to be used as parts and projects, but many beautiful models aswell. Out of the current 17, half would be road registered and half in various states of dismalntlement or repair.
5 for me:
1986 325e (4door, auto)
1986 325e (2door, 5speed)
1988 325i (for only a few days, gave it to my g/f after she wrecked her ford)
1991 318i (cabrio, 5speed)
1992 525i (5speed)
Plus the other 2 e30's in the driveway (my parents) which I am responsible for the maintenance. Graham, I want neighbours like yours! Dare I mention that I had a 1992 VW Jetta before I picked up the 525i?!!! Big mistake.
Okay, the 1988 325i is mine again as of today... so there are now 5 BMW in the driveway/garage
the 520 was a beater with body damage, but those cars around here are kinda dime a dozen too. any way when i when to register it again it needed more work than i had time for and i got the touring. The other 320i was a two door and fun as hell. but i sold it before i deployed a few years back
BTW the e30s that i had were both very low to the ground and i managed to mangle the oil pan on the first one (just before i sold it....) (i fixed it before i sold it lest ye think i am evil)
