Just had the one 911. A 1989 964 Carrera 2 bought for £24k in 1996, couldn't afford a 993. Put 50 k miles on it and sold it in 2000 for £20k. Running costs weren't too bad. If you kept it tracked it was a stunning car to drive. I had the speedo needle lying on the 170MPH mark on the autobahn until I figured I might run out of skill and hurt myself. Tempted to buy a 991, a left hooker for European trips.
