I had Condon & Skelly with '28 Aero and '64 +4 4 seater, very happy with them but when I got my 5 speeder in 2013 I had to switch to Hagerty as C & S would no longer cover 3 wheelers. Very happy with Haggerty also. Glad to hear C & S has reverted back to allowing 3 wheelers.
C & HM,
Plug (Now only the +4)
