I added my Delorean to my existing policy with Allstate and had no problems. The premium as a second car was about the same as my primary car, a Mitsubishi Diamante. I do not carry collision on either of my cars, just liability, uninsured motorist, glass and comprehensive. Maybe Allstate knows the DMC-12 a little better because as I recall they were an original Delorean investor or promoter. Jim
