I tend to get attached to all of my cars. I wish I had kept the first BMW I ever bought, but I did keep the first new E46 I ever bought, I love the lines of that car. Its a 2001 , right before they changed the signal lights a little. To me that car is classic. I just finished pouring the floor in a new 40' X60' garage. I always have it sitting next to our 69 Camaro. IDK why those 2 cars remind me of each other. Timeless.
I'm on the hunt now for a clean E30 to start restoring.
